Professional :: Stop Caching URLLoader Accesses In Flash Development Environment?
Feb 25, 2010
I'm loading an external XML file when in the Flash development environment. ActionScript 3.0 (CS3) accesses the XML file using URLLoader. Everything is fine until I have to make changes to the XML file. When testing the Flash application while in the development environment, it does not see the changes I made to the XML file, because the URLLoader is somehow caching the results. Thus, the XML file looks exactly the same. This is very frustrating. Is there any way I can blow out this cache so that URLLoader is forced to load the XML file? Currently, I either have to re-start the Flash environment or change the name of the XML file.
- One with my flash sources named "flashsources" (with *.fla, *.as etc) - Another one for production only, named "www" (with *.swf, *.html, *.js etc)
When I compile my swf, from the *.fla which is in flashsources, it is published in.I am loading an external swf from my main swf, this external one is located in www.The path to this swf changes whether my main swf is executed from Flash (at the compilation, then the current directory is flashsources) or outside Flash (running directly the file *.swf, so the current directory is "www")Does anyone know if there's a way to detect whether I am in or out Flash, to change the path to the external swf accordingly, or maybe a way to detect the current directory?
I put a swf file on a website, then I made some changes and replace the old version. However, some browsers seem to have some kind of cache to remember the last swf file, they only show the old version instead of the new one. What can I do to stop the browser caching the old version?
When not cacheing an HTML page, any movies or anything you load INTO that flash file through loadMovie or loadVars still gets cached... I use senoculars script to prevent this...
[URL]
and 2) Yes you can stop the cacheing of your page...
[URL]
Use this information wisely my friend
i came across this post by lostinbeta to stop cacheing, but the link for the one to stop cacheing files loaded through loadMovie and loadVars doesn't work. know how to get to it, or what the as was?
I need a way to stop XML files from caching. I have tried the xmlfile.load(file.xml?uniq=somerandomnumber) method, and it doesn't seem to be curing the problem. I understand that this can be stopped with PHP, however, I cannot use PHP for this task.XML caching is not a problem locally, only online, from the browsers, I cannot use any browser addons either as this file will be displayed to a vast audience and I can't expect anyone to;
a) get an add on
b) clear their cache everytime they want to see the file.
When I apply a 3D tween I get the following error when I test the movie: Error initializing Java Runtime Environment. You may need to re-install Flash If I remove the tween, no error on testing. Is this a bug? I am using CS4 on a brand new Dell M6300 mobile workstation.
Using Actionscript 2, I'm a bit new to all the scripting stuff.I have a loader loading a couple of flash movies like this:loadMovieNum("sound.swf", 1);loadMovieNum("logo.swf", 2);loadMovieNum("mainmenus.swf", 3);Those 3 movies I need to go to the main section of the site. However, I would like the loader to also load the remaining movies needed to further navigate the site, but without displaying them now Kind of like 'caching' the rest of the site, so when the access is needed, there's no load time.
I have a flv file that is being played and then after its finished another file with the same name has been recorded the problem is that when the new file is played if the browser window hasn't been closed then the old file gets played......How do I stop the browser from cacheing .flv??
Is it possible for me to have my SWF files NOT be cached by browsers? The reason being is that my main navigation system is set up in Flash, but it doesn't seem to load the "newer" versions unless I clear my cache first (when viewing in Tomcat anyways...)
i don't know how to say that in technical terms. and i think this is the reason to why i cant get good answer from Google.i have xampp on my local winxp machine. i use it for developing websites locally then upload these files to my clients shared hosting accounts.
the problem that in 2 years i have always found differences between how xampp works and how the web server work.some code work locally but dont remotely and the opposite. also flash behave differently on xampp than the remote web server.is there is a way i can get the server configuration and use it with xampp like get the server php.ini and use it with xampp?
I have a swf file imbedded in a HTML. Acceess to the file are controlled by passwords, stored in a XML-file I want to limit the number of accesses for each visitor to let us say 10 visits. How do I count (and store) the number of logons for each visitor? SharedObject works only at clienside, but iI want i serverside. The "easy" way would be to save the number of accesses for each visitor in a text-file but Flash and save... I hvave tried ExternalInterface calls, PHP etc and etc, but cant find a way that works. This is the last obstacle in a huge project.
I've been given a Flash tutorial to post to the corporate website that is an .exe file with an embedded Flash player. Users will be on IE, so I guess they would get the run/save prompt. I don't like this and I know it generally isn't done, but I need to know if it is OK to just do it. When I try to explain the security issues with executable files, eyes glaze. Is it possible that the users' system admins would be able to block the run prompt and make the user save the file? Could they block that too? The user community is hopeless, so having the embedded Flash player could be a good thing.
The only thing I get is a swf file.I don't really know why Flash CS 5.5 refuses to generate my project's apk file since I've never encountered a problem like this before. Is it a bug or am I doing something wrong? My player is set to AIR for Android,I have my certificate,I don't get any errors, and debugging on my device via USB works flawlessly.
I am designing a website with flash video content. If I pass in the URL to a .flv file as a flash parameter to the embedded video player someone can easily extract the URL and download the flv video file. How to do I prevent this? Can someone refer me to anti-leeching techniques being used my websites like youtube.
Looking for any help you might be able to give me with this one. Recently upgraded from Flash CS3 to Flash CS5 Pro. When I publish a movie produced exclusively with CS5, the resulting SWF will work everywhere but inside my company's highly restricted/locked down network. When I attempt to load the SWF in a browser from within the network, all I get is what appears to be the standard Flash preloader - the 5 little dots that crawl across the middle of the screen.
I've confirmed there's no IE version error, the machines have the newest version of Flash Player; the only difference is the network. What could be preventing the SWF from reaching the browser? Is there any esoteric publishing setting I can use in CS5 pro that I should try?
I've been searching on google and through forums for hours now trying to find a way to prevent my site from cache in browsers. I know it's not possible to "prevent" it from caching, but it's a way to trick the browser into thinking it needs to load the SWF again instead of just getting the one from the cache.Now I've tried many types but I can't get it to work. I don't understand how to implement it into AS or Javascript and what goes where.My site is set up by one parent SWF combined with a HTML script and 6 child SWF's, and they are updating all the time so I really need this function.The most used one is this I think or something close:
i got a .fla file about 2xx mb (contain number of actionscript and layers) on another using Flash CS3 Professional and i use it ( Flash CS3 Professional) too ,
i can open the fla successfully , but when i try to export the fla to the swf
it appear the message : "Error initializing Java Runtime Environment , You may need to reinstall Flash."
result : the swf is gen but the frames move "non-stop" automatically
i had tried use different OS (winXP , Win7 ) and JRE
I'm currently on a Windows 7 64bits system and I've got this unsolved problem of "Error initializing Java Runtime Environment. You may need to reinstall Flash" pop-up at Flash CS5 launch. This error (apparently relied to AS3 compiling machine) also appears during SWF compilation (so the compilation is bugged and the SWF is unusable) I've googled it and tried every piece of answer but none of them worked :
- Re-install Flash or Java (32 & 64 bits) - Delete CLASSPATH in environment variables - Reduce (or raise ?!) -Xmx128M environment variable - Launch application with XP SP3 compatibility
Is anyone here had the same problem and succeed to pass through in any kind of way
1. I've read that when Bitmap Caching an object, if the objects you are caching are bitmaps that all point to the same bitmapData object, than only one instance is cached and used by the GPU. However, if the bitmap contains a scale, does this hold true, or is a new bitmap cached for each object because of the new scale? I'm pretty sure its the second one, just checking.
2. When using cacheAsBitmapMatrix, I've seen examples setting the matrix to identity, and setting it to the concatenated matrix of the bitmap object. Can someone explain the difference between the two approaches? I would assume setting it to identity doesn't scale it up or down when caching is as stated in the documentation:
"The matrix transformation you apply to the cacheAsBitmapMatrix property is applied to the display object as it isrendered into the bitmap cache. Thus, if the transform contains a 2x scale, the bitmap rendering is twice the size of thevector rendering. The renderer applies the inverse transformation to the cached bitmap so that the final display looks the same."
But if this bitmap is nested in a sprite that moves throughout the scene, will the bitmap still move with it? Or will I need to update the matrix's x/y everytime I update the sprite's x/y. If this problem exists, does using the concatenated matrix get around it.
3. Finally, I have seen some sites state that more gpu memory is used when cacheAsBitmapMatrix (such as an additional copy of the texture being pushed into the gpu), but I was under the impression that this would just rotate and scale the texture in memory using openGL matrices. Why would more gpu memory be used when cacheAsBitmapMatrix is set?
My understanding is that when designing for mobile, if the graphic isn't too large, and the object doesn't contain nested animating objects, the best approach is to cacheAsBitmap and cacheAsBitmapMatrix on the object to ensure it won't be pushed to the gpu each frame, but feel free to correct me if I'm wrong. Adobe states "Always set the cacheAsBitmapMatrix property whenever you set cacheAsBitmap to true in content created for mobile devices."
Does anybody use bare .SWF files as webpages? I know it's possible; it seems to work fine for me. Why would I embed a SWF inside an HTML page if it's just going to be full screen (I mean the size of the browser's normal viewable page area, not COMPLETELY fullscreen)?
Is there a lack of browser support? Or is this functionality determined by the browser's Flash plugin?
I want to have a web site which switches the web camera of users, makes a video recording and send results to my web server.Is it possible to do that? I think it should be. For example such sites as chatroulette.com starts web camera. Should it be done with the Adobe Flash technologies? Is it hard to do that?
If I load a web page full of other files, e.g. images, my browser doesn't load them all at once.I seem to remember reading that IE will only have at most 3 requests open at a time for a page. The rest will be queued.If I have a flash movie on the page which is continually making image requests, how does this affect the maximum number of downloading files in the browser?
Is this browser limit accurate, and is it generally the same across browsers? Does flash share the requests of the browser? If not, does flash have a limit and what is that limit? For some background, I do have a flash movie that is continually loading files so there is a queue of Loaders waiting to make requests.My idea was that if there was a different request that I needed to be executed straight away I could make it jump the queue by making a javascript call and allowing the browser to make the request instead.
I have this PHP page that lists several people. When someone clicks on one of the people they are sent to another PHP page that has their video greeting in a .swf embedded into the page. This works by the php writing the path to the greeting video to the xml file that the .swf loads and plays.
Well in firefox it works perfect, but in IE when they try to click on another greeting the original greeting still plays. Its like the swf is caching the first greeting and refresh of the page does nothing to alleviate this. Is this a problem with the swf caching? or XML caching? or am I totally clueless?
My OS is Win 7 and I have the windows test versionof Flash Builder Burrito.There I can only develop for Android devices.I've heard it's only possible to develop forthe iPhone/iPad with a Macintosh computer.Or is there a trick to develop for iPhone/iPad on Windows PC with Adobe software(because I don't want to pay a second time for Adobe software for MAC)and only copy the result to a Macintosh? Is it possible in the MAC version of Flash Builder Burrito to develop for iPhone/iPad (and also for Android)?Or have I to use a different IDE for iPhone/iPad apps becauseApple wants native apps and Flash builder burritois only for AIR/Flash app development?
I don't want Flash to store the video and image files it pulls in when I test publish the swf. Somewhere it's keeping those files in cache, making it impossible to test a realistic download situation ( such as loading indicators, buffering bars, etc ) because the 'loading' file is immediately available in its entirety due to being stored in cache.
