Subject PerlPassEnv and Proxies
Date Mon, 18 Feb 2002 13:31:57 GMT
Hi all,

I'm using a typical dual-server combination for mod_perl content on a
selection of sites.  Requests go to the vanilla Apache and a
mod_rewrite/mod_proxy combo forward them on to the mod_perl Apache.

As part of this, I'm trying to allow a prefix to the URL path to set an
environment variable I can then use in my mod_perl programs to determine
databases, templates etc.

The vanilla httpd.conf features a line thus:

   RewriteRule ^/(test|access|ewok)/(.*)$
   http://spare.article7.co.uk:8080/page/$2 [P,E=A7_FRAMEWORK:$1,L]

(ignoring the wrapping).  I also set PerlPassEnv A7_FRAMEWORK in my
mod_perl httpd.conf -- but that environment variable always remains
undef. The order of the P,E,L flags doesn't seem to make a difference.

I appreciate that this is perhaps more of a mod_proxy issue than a
mod_perl one, but I suspect I'm not alone in having tried something
similar.  I haven't found anything in the guide that deals with this
specifically (I really don't want to append the information as a query
string), but if I've overlooked anything, I'd be very happy to be
corrected.

Many thanks in advance,
Andrew.
