Mailing List Archive: RewriteCond not evaluated for backhanded pages?

Ok, I'm confused here. I'm trying to use mod_rewrite to migrate an old
domain name to a new one... so I have this:

RewriteCond %{HTTP_HOST} abc.defg.com
RewriteRule ^/(.*) http://new.hostname.com/$1 [R,L]

This works for all pages not backhanded. Anything that is backhanded
gets shown to mod_rewrite as a 'subreq', and no RewriteConds seem to be
evaluated (other rewrite rules are eval'd).

We currently use a setup like so:

<Location /js.php>
AllowOverride None
Options None
Order allow,deny
Allow from all
Backhand byAge 6
BackhandFromSO libexec/byHostname.so byHostname (js)
Backhand byRandom
Backhand byLogWindow
Backhand byLoad
</Location>

So requests for x.php never hit the RewriteCond. I get entries like this
in the rewrite log (RewriteLogLevel is 5):

x.x.x.x - - [26/Mar/2004:13:06:50 -0800]
[lhh.careercast.com/sid#810eb34][rid#8120414/subreq] (2) init rewrite
engine with requested uri /js.php
x.x.x.x - - [26/Mar/2004:13:06:50 -0800]
[lhh.careercast.com/sid#810eb34][rid#8120414/subreq] (1) pass through
/js.php

Is there a reason for this? Am I crazy? We have found a workaround, but
it would be nice to have this ability.

There is a reason for this. Though I could be convinced that it is
invalid is someone can show me a sound alternative :-) mod_backhand
hooks Apache at the post_read_request phase so that is can get the
completely virgin URL. It was important to do this as other modules
play evil tricks on r->uri (like mod_proxy).

The way we did this is how you did it... We also used virtual hosts for
the specific situation you described.

<VirtalHost _default_:80>
all your conf
</VirtualHost>

<VirtualHost abc.defg.com:80>
ServerName abc.defg.com
RewriteEngine On
RewriteRule ^/(.*) http://new.hostname.com/$1 [R,L]
</VirtualHost>
