Hi Joshua,

first, thanks for the info.

Anyhow, a few questions:

ehem - could you explain that to me? I don't see the sence. If you're
hinting that I could figure out wether a module is installed or not,
I can see that via server-info - or do I miss your point here?

ok, will do that

hm, if it's really that, this would be bad news. Can I find this statement
somewhere in the docs (didn't find it, yet).
Currently I'm trying to write a filter in Tomcat to set the
Expires-Header, however, if I use

createExpiresHeader()); in the doFilter(...)-method of my filter, the
header also looks somewhat awkward:
(the createExpiresHeader() creates the date-string)

Expires: Thu, 01 Jan 1970 01:00:00 CET, : Thu, 3 Aug 2006 20:13:10 CEST

Seems I don't have any option to unset the header first. To me this would
look like a bug in Tomcat, since I'm expecting the method
to SET a header and not APPEND any content to an existing one.

I can, however, unset the header using mod_headers, currently I'm looking if
there's any regex to SET the header via mod_headers to the current date/time
plus 1 month - any idea, how I could do that?


what's puzzlin' you, is the nature of my game
