Javascript :: Flush The DNS Cache Or Force A Host Name To Re-resolve In Adobe AIR/Flash?
Aug 9, 2009
AIR seems to keep its own DNS cache when an application is running, and ignores any changes to the OS DNS cache (i.e. ipconfig /flushdns.More specifically, I'm creating multiple URLStream & URLRequest objects over a long period of time in a AIR application. Once the first one connects the host's IP address is cached for the lifetime of the application.And the URLRequest.useCache property,understandably,has no effect on DNS caching.how to force a host name to re-resolve inside a AIR (or Flash) application?
Note: Unfortunately, resolving the IP through a web service and rewriting the URL is not an option as a workaround.The use-case is downloading files from Amazon S3 using signed URLs which are invalidated if modified.
Update: The test results above were gathered on WinXP prior to AIR 1.5.2. Subsequent tests using 1.5.2 show serialized requests with URLStream.load() are re-resolved more frequently but still ignore TTL values.I still haven't figured out what conditions are necessary to trigger the re-resolution, but have noted a couple of cases that prevent it.For instance, if another asynchronous URLStream is active to the same host then requests use the cached IP address and are not resolved. And simply closing and dereferencing all streams to a host is not sufficient to ensure the same host name will be re-resolved in the next request.
When I deploy a new .swf file in an HTML file as shown below, I have to clear the browser cache before the new .swf file loads in the browser. Is there anyway to force the browser to load the .swf file when I replace it with a new one on the server.
I do not want to intertop between c# and AS3 or here. I want a full screen content player in C# which can host a Adobe Flash swf file. Is there an example? In full screen, right clicks would have custom behavior attached.I saw one in Visual c++. As per Chris's I checked the link. I tried adding these lines of code:
Whenever I update the flash movie on my website, the changes don't affect the appearance when people (who have already been to the site) visit the website, since the swf is in the cache. I personally, go to my temporary internet files, and delete the swf from there, so that I can view the changes from the browser. Is there anyway to force the swf to be loaded again (although it resides in the cache memory)?
I make a swf for my site that includes dynamicly loading thumbnails from an xml file. Unfotunatly the browser ( IE and FF are what i have tried so far ) just takes the xml file from the clients browser cache even if i have changed the xml file on the server. So the only way my visitors will see my updated content, is if they clear their cache every time before they visit my site. ( even a ctrl-f5 does not seem to do the trick )
is there a function or something i can call to force the swf to re-download the xml file every time? (is really small, less that a kilobyte or two im sure.)
We are running Adobe FMIS 4.0. We have five "applications" which host stream video material just fine. Recently I was asked to host an "Adobe Presenter" presentation (html file, viewer.swf and a file full of xml and swfs) I have spent three days trying to get it to run. I can link to the Presenter presentation if it is hosted on public network storage, but I can not seem to get it to run under an application in FMS?
I currently have the latest version of the IE Flash Player Installed: I've installed the latest version of the content debugger from The Adobe Flash Player Support Center. Regardless of what I do IE doesn't seem to pick up the new content debugger version. I've tried uninstalling, tried installing an older version... All with no luck.
I'm using a modal window on a client's site where we have no access to the content. The problem is that he has some flash on the page and the wmode for these is not set to transparent.
Is there a possibility to force their flash from our javascript to have this parameter added?
I'm building a mobile MP3 player with AIR, which streams audio using the Sound class's .load() function. I'd like to cache this audio as it's downloaded, to the the user's SD card. Is this possible without having to download the file twice??
I am working on application to open cpanel (web host server) in Adobe AIR. I know how to open a web page in Adobe AIR, but I don't know how to open cpanel with username and password?
Does anyone know if adobe flash player cache data is available to other users on a system? For example: A user logs onto Windows XP, then uses my adobe flex application... and in the process of doing so downloads the signed flex lib... He then decides to mow the lawn and log off. At about 3pm the same day, his Mum can't hear the TV over the sound of the mower, so she decides to log in using a different XP user account. She proceeds to use the very same flex application. Does she also need to download the flex lib again, or would the data already be cached in the flash player?
I have a media player, which rotates images for the artist it plays. I load the images dynamically into the flash. The flash downloads the same images from the server over and over, how can i cache the images, so flash grabs them from a local cache and not from the server?
I have a pdf which opens when a button is clicked on and i was wondering if there is a way that i can force it to open in adobe reader instead of ie or firefox?
We have an Air and Flash application that opens a pdf, but many computers by default open pdfs in browser plugins rather than through reader itself. Is there a way to force the alternate behavior in Flash/Air? This is needed since we have slightly writable pdfs.
I am using swfupload to upload files on a website, the problem that every time the user open the page which contains the upload button, the page loads completely then the flash file start loading from scratch every time the user visit the page with no cache. Is there a way to preload and cache .swf files in my asp.net page?
Right now, I'm doing a lot of byte write operations, and I believe this is taking up a bunch of memory, which is then throwing an error. Is there anyway to flush some unneeded memory every now and then? It's not flushing the memory every time I run it in the fla either.
I developed a flex website, the web explorer always caches swf file which embedded in HTML. Sometimes I make changes to the flex file, clients computer still view the previous version which stored in cache. How can I force client's web explorer to reload/refresh the swf file?
I've made a custom video player in as3. Everything works, but once a video has loaded and played through completely, if the user replays the video it continuously fires the NetStream.Buffer.Flush event until the video stops playing again (by either ending or by the user hitting pause). It doesn't seem to effect anything negatively, but I would rather not have an event continuously firing in the background like that. I can't find any documentation of this happening online anywhere. Is this normal behavior for a NetStream that has fully loaded?
Create a full page background image slideshow like [URL] using Flash? I'm new to flash and I want to know hoe to create these full screen image slideshows, that start on page load and scale proportionally just like the above two websites, using Flash CS5 AS3.
I notice that, when I pause the video, the event "NetStream.Buffer.Flush" is triggered. And according to the language reference: "Data has finished streaming, and the remaining buffer will be emptied.", I have to re-buffer it, right? However, also according to the reference, it shouldn't stop buffering:
Starting with Flash Player 9.0.115.0, Flash Player no longer clears the buffer when NetStream.pause() is called. This behavior is called "smart pause". Before Flash Player 9.0.115.0, Flash Player waited for the buffer to fill up before resuming playback, which often caused a delay.
I'm using Flash Professional to do the debugging, and the traced version number is: MAC 10,0,22,91, and it appears for both FMS4 and red5.
how to best handle the issue of not having enough permission inside of a Google Chrome Extension. I am interacting with the YouTube API, but I am not using swfobject.js, just using am embdeeded div. I do not believe this is introducing my security issue, but perhaps it is. In development, I had to navigate to Adobe's flash player security page and designate my development folder as a 'safe' location. In deployment, I do not have the ability to do this. I do not want my users to have to click 'Allow All' on flash player security, but I do not see another way to achieve my results.Seems to be a duplicate of SWFobject in a Chrome Extension - API Unavaiable but remains unanswered.Source: https:[url].....
To run: Pull from the repo, load up Chrome, click the wrench, go to extension, check 'Developer Tools' -> Load Unpacked Extension and browse to the folder.
I am using flash builder 4 to run sample application from "Getting Started with FLEX 3", but the code can't run because there is one place that FB4 can't resolve, I guess this is because the library has been obsolete but after a tons of search I can't find the solution.
I remember doing this years ago, but can't remember if it was with SWFObject. Anyone herd of this before? I guess it would basicly disable SWFObject from switching the altContent for the SWF. I though it was something like: [URL] But can't remember the real one (if it exists).
I am using Flash Builder 4 and need a VideoDisplay component that works with Cue Points. The newer version of theOSMF classes that Flex's VideoDisplay are based on handles this already. The idea is to roll my own VideoDisplay component rather than monkey patch the existing one. To do this, I have created a project with the newer version of the OSMF classes, and another project with which I would build the new VideoDisplay, in a separate package name.
The issue is that since the Flex 4.1 SDK contains the majority of the OSMF classes with their original package names, a statement such as import org.osmf.media.MediaPlayer; references the class located at
I am a web designer and I do like to hand code using jquery however, I think it would be much faster to use gui applications like flash to create animations especially on the fly as well as support for writing and editing source code.
I've been working for a month on a flash game, which should be manageable to play in a browser (light computation). This being said, I've noticed that in some browsers the game runs at what looks like 15 fps (the game should run in 80fps). This has been known to happen in IE9, and the quick fix was to add this line to the top of the html: <meta http-equiv="X-UA-Compatible" value="IE=9"> This was a quick-fix that forces IE into compatibility mode and greatly improved the fps (to about... 60, let's say). Still, I believe that the game is running slower than it should in every browser, which is evident when the html version is compared to the swf.
