Hi,

I support SSIT infrastructure, not WEBSIS directly or web browsers, but 
I have a few comments.

If the server fails to send a mime type, then the browser uses its own 
mime type table (a fundamentally flaw in web browser design, in my 
opinion, but that's another discussion).  I do not recall if the 
browser mime type table can also override the server mime type.

There have been reports of various problems with WEBSIS that have been 
verified on specific versions of Mozilla on Linux being used.  I was 
involved in the solution of an especially subtle bug involving secure 
connections and a particular kind of redirect to another server, where 
the Linux version behaved differently from Windows or Macintosh 
versions.  So, platform specific bugs do exist in the browser 
processing of server responses, and they have been seen to be related 
to secure connections, which comprise most of WEBSIS.

Based on my knowledge of the WEBSIS script designs, a mime type is 
always sent.  The WEBSIS team can double-check the script in question 
for errors, of course, but I suspect that nothing is wrong with the 
script.

My two cents.  I really do not need be copied on this exchange, btw.  
The WEBSIS team will contact my team with any blocking infrastructure 
issues, once they have time to address this issue.
