All that html metadata does is assure that the HTML code will be refreshed each and every time the viewer sees the page. But to my knowledge this does not affect whether a media asset such as a flash document (SWF) is refreshed on each pageview.
It is impossible to prevent a SWF from apprearing in the browser's cache folder. But you can insert generate the embed and param tags dynamically with javascript, and then using something like: "myFile.swf?nocahe="+(new Date()).getTime() (not excatly sure of the syntax, it's been a while) ...you can assure that the browser will load the SWF anew with each page view/refresh so that the SWF is being fetched from the server each time versus from the browser cache after the first view. But the file will still appear in the browser's cache folder no matter what you do, including runtime loading of a content SWF into a proxy. I suppose, theoretically you can stream the content SWF from a streaming server such as Red5 or FMS into a bytearray in a host SWF and convert the bytecode into usable content, but I've never tried it, and do not know how you would implement the particulars. This would be the only way to ensure that the SWF never appears in the browser cache. Usually it's more important to secure the data in the application than the application itself. Better to apply a bytecode obfuscator than to go through all that trouble unless you're doing work for the military or something. _______________________________________________________________________ Joseph Balderson | http://joeflash.ca Flex & Flash Platform Developer | Abobe Certified Developer & Trainer Author, Professional Flex 3 (coming Winter 2008) Staff Writer, Community MX | http://communitymx.com/author.cfm?cid=4674 mailamannow wrote: > Hi > > Following is the Code available at > http://livedocs.adobe.com/flex/3/html/help.html?content=performance_05.html > > (1)Where exactly to use it so as to prevent client side caching? > > Cache-control: no-cache, no-store, must-revalidate, max-age=-1 > Pragma: no-cache, no-store > Expires: -1 > > (2)is there a better way to prevent that when i m not using php, jsp, > https service, flex data service, and all > the stuff whose tutorials are mostly available when i google for the same. > > i simply want my swf not to be cached by the browser. please guide > > Thanks > > > ------------------------------------ > > -- > Flexcoders Mailing List > FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt > Search Archives: > http://www.mail-archive.com/flexcoders%40yahoogroups.comYahoo!
