Flex To Load Cached Preloaded Images?
Apr 5, 2011
In 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 little app that can read and write content that is stored in XML files. As those files get updated and re-loaded quite often I have made the experience that the browser tends to use the old/cached XML-data. Can I somehow flag the URLLoader that I use to load the XML to always load the actual file instead of looking for cached versions?

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?

I 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.

I have a button that loads guestbook.swf. As guestbook would be updated by me I would like the latest non cached version of guestbook.swf to load always. This is the code on the button currently. What would the code look like to load the latest version from the server? You know some random number/date time stamp thing? I tried using some Googled AS2 code off the web and the button stopped working.[code]

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.

We 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.

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.

I need to load several images as Bitmap or BitmapData objects. The images are hosted outside the Flex project, and they're referenced by an external configuration file, so I can't embed them. Because the images won't be displayed directly to the user (they're being added to a PDF that is generated for download), creating a grouping of Image objects, attaching them to the application, and waiting for their LoadComplete handler to fire seems inefficient.
What is the best way to load these images into an application? Programatically load images in it?

I'm building a slide-show like application in Flex and I'm trying to load images dynamically. The images are in a folder outside the application folder. This is the folder structure:
/Bildvisare-debug/
Bildvisare.html
Bildvisare.swf
/Images/
[Code]....
The problem is that the images never show up, I only get the icon for a missing image.
Edit to add: I've tried this both with and without the use-network flag set to false when compiling.

I'm trying to load a bunch (about 100) of images into memory, so I can display them at various times. Originally I had simply embedded them, but that of course resulted in the swf file being larger than I wanted. So now I'm trying to change it to load them in the background because they aren't needed immediately.There are probably plenty of problems with this. The current on is that I'm getting an error that says 'TypeError: Error #1034: Type Coercion failed: cannot convert "foo.jpg" to Class.'
I've been googling this awhile, assuming loading an external image is a common thing. That's where I got the Loader and URLRequest code, but I'm clearly missing something. Maybe it's due to my goofy looping logic.Here's the class so far
public class CardImages2
{
public static var fooImage1:Class;[code]....

So I made a drag and drop app where I can drop in an image, it get's resized and saved automatically on the desktop.
But now I want to do the same when there are multiple images dragged in. This is where I'm stuck...
private function onDrop(e:NativeDragEvent):void
{
trace("Dropped!");
var dropfiles:Array = e.clipboard.getData(ClipboardFormats.FILE_LIST_FORMAT) as Array;

The problem is that I want the completeHandler() to run after every ldr.load() but in my code it only runs once right after the for each loop.

I'm developing an application for the Blackberry Playbook using Flash Burrito 4.5 and Flex. I'd like to create a file browser to allow users to load images from the local system into the application. I followed this example [URL] When I click on the Load Image button in the simulator however, the file browser pops up but tells me that "no file was found with the specified filter", even though I don't specify any filter or even if I specify a . filter.

I am trying to load multiple images into a scene and then cycle through the images one at a time.So, here are the essentials what I've put together in AS3:First I set up a counter and a Loader
[code]....
Then, after loading a list of images from an XML file, I call a function that I called "createImages". This function then takes the list of images and creates a bunch of loaders:

So far, so good! I now have a bunch of loaders each with a different name "img1","img2","img3" etc.

I am using actionscript 3. I can load an image in a class but how do Iload a number of images eg 4 images that animate.?These 4 images are a walking sequnce of a character. I am unclear after googling an loading multi images in as3( just love google).
Loading a single image I load this into a loader Once loaded I load the image into a bitmap and add to a sprite I then add the spite to the stage Q)Now for 4 related images I load 4 loader or 4 sprites or 4 bitmaps or do every thing 4 times?I want to do collisions eventually and I need bitmaps but bitmaps seem useless to use other than collisions.Googling for answers isnt helping me clarify this!

I have a rotaing menu that loads in images from an xml file, I would also like it to load in text info from the same xml file to the left side of the images that load in. In my main .fla have created a movieclip and called it 'textInfo' and inside that I have two dynamic text fields called 'headerText' and 'bodyText' where I want to load the text in. this is what I am using to loading in the text in my actionscript, is this correct?

Hon the wallets page, when you click to view a wallet you get a slight delay and I'm guessing that this is because I've put the preloader in the swf being loaded, hence not being able to see the thing your loading until its been loaded.how I would put the preloader in the main movie and what kind of code I would use? At the moment the timeline being loaded basically tells the playhead to goto and play frame (whatever) when the movie is loaded.

I've found lots of answers on making a button visable after a swf has loaded but not a flv. I am preloading an flv, well 20secs of it, then it starts playing. But I have a 'play' button on the stage and it sits there tempting people to hit it whilst the preloading bar works its magic preloading the flv. I want the button to be visable only after the flv has loaded or at least until it starts to play.[code]

I have a container swf that preloads 4 other swf's and the user can navigate between all 4.
The problem is that once loaded, the animations for all the swf's begin immediately. So the animation for the 4 swf could be finished before the user ever sees it.
I've tried reloading the swf as a new URLRequest, but that caused an issue: when I test using a simulated slower connection it causes a slight delay in the loading of the swf.
Is there a way to restart a preloaded swf?

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.

Is there any way to get the logo on screen before anything else comes up rather than just having a black screen? (without breaking the main movie into smaller ones).
