This is only peripherally related to AOLserver, but there are so many
helpful and knowledgeable people on this list, I'm hoping someone will
recognize this.
I'm still working on that Apache/Tomcat caching thing I wrote about a
few days ago. The client is insisting on Apache and nothing but
Apache, so I haven't investigated Squid, Varnish or anything else so
far.
I figured out how to use mod_cache to get Apache to cache the content,
but it's kind of useless because there's a "Cache-Control: max-age=0"
header that causes it to request a new copy every time. The problem
is, I can't figure out where it's coming from.
I've eliminated Tomcat from the loop entirely, so the fault lies
somewhere between AOLserver and Apache:
- telnet to AOLserver directly - no cache-control at all

- use mod_headers to add a Cache-Control header - now we have two:

It appears that Apache is adding the rogue header, but I don't know
how to tell it to stop!
Any suggestions?
