Hey, that solved the problem!  Try:

Actually it appears to work with IE5 as well, so it isn't being ignored in my
case.  Strange.  Can someone else give it a shot with IE4 or 5?

Upon looking more closely at the response headers I noticed that the
SSI-generated response included the "last-modified" header, and the direct
servlet response didn't.  I brutally hacked SSIFrame to remove this header
field and this solved the problem in the Netscape case, but caused IE to get
really angry and refuse to show the page at all.  I just had to try...
