What is very interesting is that I also see MenuBar.js being requested even 
though it should be cached. I guess Gecko must decide to never cache it. Weird.

Maybe that's your problem. Pressing reload is forcing the browser to refresh 
every source file from the server. 

I have our server configured to put "max-age=60" in the Cache-control response. 
That forces the browser to check with the server if any file is modified if it 
is more than 60 seconds old. So when I re-open the application, having made a 
change, the browser will check with the server and get either a "304 - not 
modified" response or a "200" with the new date.

This is an edited extract from a protocol trace:

When it's modified:

GET /user/client/source/index.html HTTP/1.1
Connection: keep-alive
If-Modified-Since: Tue, 06 Mar 2007 11:54:11 GMT


HTTP/1.1 200 OK
Date: Fri, 27 Apr 2007 06:48:19 GMT
Connection: keep-alive
Last-modified: Fri, 27 Apr 2007 06:48:10 GMT
Expires: Fri, 27 Apr 2007 06:49:19 GMT
Cache-control: max-age=60


Note max-age=60. Then later on:


GET /user/client/source/index.html HTTP/1.1
Connection: keep-alive
If-Modified-Since: Fri, 27 Apr 2007 06:48:10 GMT


HTTP/1.1 304 Not modified
Date: Fri, 27 Apr 2007 06:55:14 GMT
Connection: keep-alive
Last-modified: Fri, 27 Apr 2007 06:48:10 GMT
Expires: Fri, 27 Apr 2007 06:56:14 GMT
Cache-control: max-age=60
