Maybe:

hmmm, I don't know the AxKit architecture really, but I don't think you can
get rid of the Last-Modified header when using default-handler since it
calls set_last_modified() explicitly. IIRC AxKit uses the default-handler as
its caching engine, right?
if that's true, you might want to try fiddling with mod_expires and see if
you can get the results you want from it.
from mod_perl you might be able to enforce a stale page by setting
$r-mtime(0) before the Apache default content handler runs, which ought to
result in a Last-Modified header of Jan 1, 1970 (untested, but I'm pretty
sure I tried it once)

It depends :-)
But yes, you might be right, depending on how the content gets delivered.
You could always add in a blank AxOutputTransformer, which will force AxKit
to just use print(), even for cached content.

I don't see AxOutputTransformer in the docs...do you have an example
which would do this?
(the $r-headers_out-unset didn't work)
Thanks!

Off the top of my head:
package MyDeleteLMod;
sub del {
Apache-request-headers_out('do whatever'); # not sure this is needed
return @_;
}
1;
then in httpd.conf:
PerlModule MyDeleteLMod
AxAddOutputTransformer MyDeleteLMod::del
I'm not sure you need to actually munge the headers if you do that or if
it'll influence AxKit's caching by itself (it always runs after caching).
