First observation I would make .. why do you use so many (30+) embedded SWF files?

You can pass vars (to control different views) from an external XML file, or internal XM 
dataset.

You need only one SWF file if you use an oen source Flash (RIA) development environment 
like ....

Or if mixing with HTML content, make your toolbar just one SWF file.


On the subject of IE caching .. more here ..

All the more reason, surely, for having a single load, single SWF application, with one 
SWFObject call onload.


If you are inspecting HTTP requests/responses, this proxy tool is useful (and free - IEWatch 
is not free)


http://www.fiddlertool.com

Launch the url in IE browser then click Session Inspector.

You can see the multiple requests for /flash/swftib.swf

Also if you dump the session report - Edit > Copy > Full Report

at caching you see this

Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0



Fiddler also works in Firefox but proxy connection has to be manually set to port 8888.
