How do you know if the browser is actually using the cached swf RSL/library for Flex projects? I would like to be able to do different things from the preloader based on whether or not the user has never downloaded the library vs. they have it already cached by their browser.
View 1 RepliesI have tried various codes (probably wrongly) and read different posts and failed to achieve what I am after. So to cut going round in circles I have just made a simple test folder. There are 3 things I am trying to achieve so that latest files are loaded instead of browser cached versions.
Everything is linked properly in the TEST folder (apart from the code to get latest non cached version)
You can download the TEST.zip folder (73KB) here- [URL] It's completely safe to download and please ignore the annoying pop up ads. I signed up for free service hence the ads.
The three things I want to achieve-
In the TEST.zip folder start with index.html.
1- There you will see >Enter Button< and >portfolio.pdf< button. Nothing will change on index.html page but the portfolio pdf will be regularly updated. So I want the >portfolio.pdf< to fetch the latest pdf always. I assume the code will go on the >portfolir.pdf< button?
2- >Enter Button< will take us to master.html page which contains master.swf. Master.html is only a container but master.swf will be regularly updated and needs to always load the latest master.swf version.
3- Load image.swf button will load image.swf. I want the button to load the latest image.swf file always.
So the following code is Lee's implementation of a preloader which works fine first load but goes crazy when the browser loads a cached file, jumping from 0% to 100% randomly Things I have tried to no avail: switching off gzip compression, tho I dont think it is on Using ENTER_FRAME instead of progress and complete
[Code]...
Is there a way to check if the user has my site cached so it can tell my preloader not to run?Or is there an easier way to check this? I have a preloader, but once it hits 100% it makes a mess. It's not all that appealing. It works if you see it loading, but just to see the mess at the end is not aesthetically pleasing.Is there a way to have the Flash movie say, "Oh. You've already got this loaded? Skip animation." ?
View 5 RepliesWe have a Flex application which doesn't currently use the Flex framework as an RSL. We're considering switching, but we're not sure what proportion of users will already have the framework cached.There's an added complication in that we're using the data visualisation components too, and we may have a choice as to which version of the framework we use.
View 2 RepliesIn my application, I make numerous calls to preload images to brower cache in the background using Loader instances and ignore the complete event. I don't store the results in the application, but rather want to store them in the browser cache. The images have long Expires header dates.
When I want to use a particular image(s), I again use a Loader instance and call the same url and listen for the complete event to load the file to an Image.
The problem is that when I re-request the url for the "cached" image, it is making an http request with response 200 status, which I presume means it is hitting the server. How do I make sure that a request for a cached image never hits the server from Flex? I am finding that any request to a url for a cached image (with a long expires header) is making another request to the server, or at least that is my interpretation of it in Firebug.
I have a project that is for several customers, the only difference is in the DB, everything else looks the same, except for the main page's text. That is loaded from an external swf file. I created a library, compiled it as an swc, imported it and using it as an RSL. The problem is that if once I've opened the page, and afterwards update the rsl (because changes in the text are needed), than it's already cached by the browser (not the flashplayer's cache but we shouldn't discuss this please!) and the updated swf won't be loaded. If I use it as an external, the page won't even start up (the browser says it's loaded, but it's blank, not even the loading progess bar of flex appear)
<local:MainPage includeIn="default" currentState="{MainPageState}" id="Page"
width="100%" height="100%" />
this is the code on the main page, if I comment this out, than the whole thing loads, even with the use of the "external" link-type. in the design view, I see the component, but I get a warning for the library:
Design mode could not load MainPage.swc. It may be incompatible with this SDK, or invalid.DesignAssetLoader.CompleteTimeout)
I'm currently working on a project that needs to request a url multiple times. Having studied the the HTTP Proxy (Charles) it seems that AIR will cache the first response and then return the same response for each subsequent request.Does anybody know how to know if the response has been cached other than setting the URLRequest to useCache, but this doesn't say if the response was a cached response or not. The digest isn't set on the URLRequest either, although it does mention this is for swz only, so how does it know if the content is the current content or not? Is the responseHeaders used to find out how long to hold the cache i.e.Cache-Control: max-age=900
Also does anyone know how to flush/purge the cache or are we at the whim of the GC and in that case how does it know if to leave it in the cache or now?This makes sense to me, but still I would like to know how to regulate this cache.Further more: I've tested a set up where parallel URLLoaders (10) are made and created which open the same url to see what happens in that instance. It seems that each parallel request is made until a successful response is given, all subsequent calls are then cached. Calls which are sent out before the successful request is then completed. It looks like the items which are already in being processed do not use the cache and return with correct data.Additional The AIR runtime doesn't even send a "If-Modified-Since" header, so the cache isn't even honoring HTTP protocol. So it seems as if Adobe has implemented it's own version of a cache which doesn't even use HTTP/1.1 Header Field Definitions.
in other words, suppose I want to send data, like text, programmatically from a Windows app (such as a browser plugin) to a Flash app running in the browser. Well, conceptually, an example of this might be a Flash instant messenger with a textbox and button "Send"; so let's say I want to be able to programmatically paste the text and press Send or otherwise activate it. That's NOT what I am trying to do here in reality (i.e., no,I am not trying to spam other people's chat rooms or anything)but just an illustration of a similar situation.I can include in it whatever widget or hack that may be necessary.The reason why this problem is arising for me is that AFAIK the SDK that is providing me the data I want cannot be directly accessed from Flash, so I need a way to pipe the data from a regular app into Flash. can I have the Flash app interact with other apps through localhost IP? Or are there draconian restrictions on which server Flash in browser can and cannot interact?
View 1 RepliesThe title essentially is the question, how do I open the .swf without the browser's control bar junk? and maximize the window?
View 2 RepliesI'm developing a flex application with 4 tabs. When the user switches a tab I want to reset the previous tab to its initial state. Also I need to alert the user, if he hasn't saved the changes he made if any, will be lost.I'm planning to set a variable in the Model, and set/reset it if any change happens in a field under a tab. But how do I monitor this? Is there any listener available for this?Also how do I check and reset the state of the previous tab? The contents that come under the tab is from components only.
How do I check if the user has made any edits in the current tab? Some fields are generated dynamically too.I'm calling a function in the onchange event of TabNavigator and asks the user if he really want to switch the tab.I want the other tab to load its contents only if the user clicks Yes to the Alert box I'm popping up. But now the confirmation box pops up, and the contents are loaded into the other tab and if the user clicks No it goes back to the other tab. How do I prevent the action of loading the contents of the other tab at all till the user presses Yes?
I am working on a game in flex, and I am trying to create an xml file for each user if it is their first use, and then after that just access that file and edit it accordingly.Is there anything that could do this same thing first off, basically create and edit some sort of save state? I assume that flex would have some kind of saving state type of thing, but I am not sure what to look for in that respect.If not, does anyone know how to do this with xml files?
View 1 RepliesSo I've got an xml like this stored in a variable in Flex AS3

I have a question about HTTPService and the data it returns.

There is the following bug in the gallery:Once you open up the gallery you see a container with all small thumbnails.If you start mouse over the main container you can see the following happen:
- shadow filter change
- quality of the thumbs change
There is a rotationY and rotationX on the main container. As soon as i remove that there is no bug and the shadow and quality of images is perfect.So what does flash do to children and their filters inside a container when using transform propertys before a MouseEvent happen to that maincontainer.You should use F5 a few times before you excaly can see it.
My question is about XML loading. I need to avoid xml caching. On a web server, the technique is adding a random param to reload each time the XML file. But on local testing (in Flash CS4 IDE, CTRL + Enter), the following lines are not possible :
var my_date : Date; path = "toto.xml?time="+my_date.getSeconds()+my_date.getMilliseconds();
Is there any trick to bypass this issue ? I've read on different forum about the "delete" method, we delete the xml object and then recreate one new.

I'm coding an audio player using swfsound for non html5 compliant browsers. I've three sample files, sound1, sound2 and sound3.
After doing some tests, I've changed sound1, with other file, but surprisingly the original remains cached in the browser. I've deleted the original file, moved to other folder, no way.
The only way to reproduce successfully the new file is to active the "disable cache" feature. I'm looking for a way or method to unload the previous file (if there's one) before loading a new one. The audio player will be playing different mp3 files, and in the way that is working now, it won't succeed.
When we reference a SWF file from our ASP.NET page we append the version number to the SWF url, like App.swf?1.1.0.0. In a recent update, Firefox has continued to use a cached swf even when the version number changed, App.swf?1.2.0.0. We haven't noticed this behavior in other browsers.
Has anyone else seen this behavior? We don't want to disable caching completely. At this point we're probably going to change the name of the swf for each version, like App.1.2.0.0.swf, which seems a bit excessive.
i had manny mp3 and wave files in library and my fla file was aprox 700MB,now i have deleted all mp3 and wave files, but the fla file is still 700MB.how is this possible?in start i have loaded wave files but at some point flash told me no memmory awailable.so i tought.ok i'll delete this waves and load mp3s insted..
View 4 RepliesI guess my question is pretty simple for some of the guru's here, but i gave up with this already Im writing an photo gallery application for a website, everything works just perfect, but i have the following problem: Im using the events onLoadComplete and onLoadStart to display an small popup alerting the user while the picture is downloading... so how could i check if the picture is already cached ?, so i could use an IF statment to only show the popup if the picture has not been downloaded before? This is the relevant part of the code that im using right now, it works perfect, but it shows the "loading clip" EVEN if the picture is already there

My problem is that once flash reads an XML, it then wont read the XML again but rather uses a cached copy. This causes problems as I want it to update a record number in the XML.
My flow of data is like this:
1)Flash reads (and presumably caches) an xml file.
2)User enters data into flash (including update data for xml).
3)Flash sends data to PHP.
4)PHP edits XML file (adds a line and updates a record #).
5)Repeat above.
In practice what happens:
I have a recorded number recorded in the XML. (say 10)
Flash reads the recorded number from the XML. (still 10)
Flash updates the recorded number (now 11)
Flash sends the number to PHP which updates the XML (so XML is now 11)
When process is repeated: Flash uses cached XML so reads record number as 10!!
I need to load a range of images and make them crossfade over time in a never ending loop (rotating gallery).
Using the Loader I display a preloader everytime I load an image.
The problem is that the next time I load the image the damn preloader shows up in a split second (because I'm using the Loader to load the image again).
How do I write the routine of loading an image and reuse it again WITHOUT calling the loader a second time?
I read online to read a the bitmapData into a variable. Well, that's all fine. But HOW do I reuse that Bitmap in a never ending carrousel?
using shared libraries at the moment for a scalable e-learning course. All the elements are to be used over multiple screens. BUT if I have to add a new element to that published shared swf - then next time I access my learning program it will have to download the WHOLE NEW shared library - is that right? ie: defeating the purpose in the first place. So if that is true then the best idea would be to use separate shared libraries. ie: sharedLibraryMusic1.swf sharedLibraryMusic2.swf for newer mp3s etc...
Or is this nonsense. ie: A new updated shared library with a "little" new element would not cause the whole swf to be downloaded again??? This is so important as it can make or break the download speeds.
We have a flash app (AS3) that reads some data from a local XML file and displays it in a cool way. The problem is that the browser(s) seem to cache this XML data, i.e. when we revisit the page containing the flash, it is rendered using out of date data (the XML file is updated regularly). We find we must visit the URL of the actual XML file and hit refresh (CTRL+F5) to get the new XML to load, and then go back to the page with the flash to see it rendered with the up-to-date data. Is there a way to remedy this? Perhaps the solution is like the one used to prevent caching of Javascript, i.e. appending a random GET param to the URL?
View 5 RepliesLook at the example: Left sqaure mc1 is cachedAsBitmap right square mc2 is usual MC.
Go mouse over the edge for scaling for both mc's. Cached movieclip goes crazy
How I can bypass this thing easily?
1. How long is an XML.load response typically cached for in Firefox/IE?
2. How long is an swf typically cached for in Firefox/IE?
I'm asking because I have an XML file that changes every few hours, and an swf that changes every few weeks. I'm noticing that the changes don't get picked up in Firefox, even after restarting my browser.
I am working on a page the allows the user, once logged in,to upload information and a picture. The picture is saved as his/her username, and if they upload a different picture, the old one is still displayed unless they leave the site and come back 10+ minutes later.I tried the HTML no-cahce headers and they don't even help load a new (up-to-date) version of the main movie.This should have an easy solution, that Adobe should have
addressed if they expect flash to be capable of being a dynamic site with user interactivity.
I'm loading an SWF animation and want to display it in multiple places concurrently, but the only way I could figure out how to do that is to load it every time I display it, as seen here:
private function playSounds():void {
for (var i:Number = 0; i < 14; i++)
{

What's the easiest way to prevent what I call preloader flicker. What I mean is the preloader works fine on first load but then once the external swfs have been cached the preloader still displays for just for a split second but doesn't have time to animate and it just looks a bit ugly. I ideally just want the preloader to appear on first load or force it to animate.
View 14 RepliesThis all works great until the items have been cached by the browser and then the movies still load but the preloader doesn't get time to animate and just shows for a split second which looks a bit crap.I read somewhere about creating an array to store the paths of all the loaded in swf's so I could then turn on and off the preloader's visibility if that file had been loaded before.This all worked great until I refreshed the browser window then of course the array got reset so all my stored values went and the preloader started to show its self again.
Then I thought could I store the array values in a local shared object but then I thought there's got to be an easier way.What is the best way of doing this?My preloader is just a bog standard 100 frame animation that go to and stops the frame of the percent loaded.
