I have a Drupal site, example.com, and our client has a campaign that they're promoting for which they've bought a new domain name, campaign.com. I'd like it so that a request for campaign.com internally rewrites to a particular page of the Drupal site. Note Drupal uses an .htaccess file in the document root.

The normal Drupal rewrite is

# Rewrite URLs of the form 'x' to the form 'index.php?q=x'.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !=/favicon.ico
RewriteRule ^(.*)$ index.php?q= [L,QSA]


I added the following before the normal rewrite.

# Custom URLS (eg. microsites) go here
RewriteCond %{HTTP_HOST} =campaign.com
RewriteCond %{REQUEST_URI} =/
RewriteRule ^ index.php?q=node/22 [L]


Unfortunately it doesn't work, it just shows the homepage. Turning on the rewrite log I get this.

1. [rid#2da8ea8/initial] (3) [perdir D:/wamp/www/] strip per-dir prefix: D:/wamp/www/ ->
2. [rid#2da8ea8/initial] (3) [perdir D:/wamp/www/] applying pattern '^' to uri ''
3. [rid#2da8ea8/initial] (2) [perdir D:/wamp/www/] rewrite '' -> 'index.php?q=node/22'
4. [rid#2da8ea8/initial] (3) split uri=index.php?q=node/22 -> uri=index.php, args=q=node/22
5. [rid#2da8ea8/initial] (3) [perdir D:/wamp/www/] add per-dir prefix: index.php -> D:/wamp/www/index.php
6. [rid#2da8ea8/initial] (2) [perdir D:/wamp/www/] strip document_root prefix: D:/wamp/www/index.php -> /index.php
7. [rid#2da8ea8/initial] (1) [perdir D:/wamp/www/] internal redirect with /index.php [INTERNAL REDIRECT]
8. [rid#2da7770/initial/redir#1] (3) [perdir D:/wamp/www/] strip per-dir prefix: D:/wamp/www/index.php -> index.php
9. [rid#2da7770/initial/redir#1] (3) [perdir D:/wamp/www/] applying pattern '^' to uri 'index.php'
10.[rid#2da7770/initial/redir#1] (3) [perdir D:/wamp/www/] strip per-dir prefix: D:/wamp/www/index.php -> index.php
11.[rid#2da7770/initial/redir#1] (3) [perdir D:/wamp/www/] applying pattern '^(.*)$' to uri 'index.php'
12.[rid#2da7770/initial/redir#1] (1) [perdir D:/wamp/www/] pass through D:/wamp/www/index.php


I'm not used to mod_rewrite, so I might be missing something, but comparing the logs from a call to example.com/node/3 and from campaign.com/ I can't see any meaningful difference. Specifically the URI and args on line 4 seem correct, the internal redirect on line 7 seems right, and the pass through on line 12 seems right (because the file index.php exists). But for some reason it seems the query string's been discarded/ignored around the time of the internal redirect. I'm completely stumped.

Also, if anyone could provide a reference on understanding the rewrite log, that might help. It'd be great if there's a way to track the query string through the internal redirect.

FWIW I'm using WampServer 2.1 with Apache 2.2.17.
