Cache-extending swf files with swfobject.js

[GoogleCodeExporter]

Hello,

It would be very useful to use mod_pagespeed to do it's cache extending magic 
on swf files. We have a large swf application which we would like to host on 
our cdn to improve performance, but managing the cache invalidation of the app 
has proved to be a major headache.

Random thoughts on implementation

- swf files can be treated as images in terms of using the md5 checksum to come 
up with a new leaf filename. Best to avoid dealing with flex modules or any 
bytecode alaterations.

- when writing a html parser to detect a swf url that should be optimized using 
cache-extension, the natural place to focus is the standard adobe template that 
uses swfobject.js. There are predictable best practice regular patterns here 
that could be recognized and rewritten. see 
http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf663fe-7fff
.html and http://code.google.com/p/swfobject/

- if swf actionscript application code itself uses the filename of itself for 
any internal logic, then it will fail.  Acceptable limitation because this is 
not a standard usecase.
