any time prior to calling $r->send_http_header() should work fine.  If you
already have a PerlTransHandler that you are using you could put it there.
Maybe others have an opinion as to the 'proper' place, but I have always
included in wherever it made sense at the time, usually in PerlHandler.

you may also want to search the archives concerning NS and MSIE caching

investigating this issue and there was a decent thread maybe 4 or 5 months
ago discussing REDIRECT to prevent caching, expire headers, etc...

Browsers drive me nuts.  I've seen this work well for Apache::ASP.

$Response->{Expires} = -86400 * 100;
