I don't know anything about JSP or Apache. But you folks do! So...
If you go to this page:
and then look at the IE6 cache files, you will see that the "Expiration Date" for the file named
is set some time in the year 2038
But if you look at the cached GIF files that come in from this page
there is no expiration date.
1) Why is that?
2) How can a site that uses JSP serve up a GIF file and specify an expiration date for it?
