Isapi Rewrite - access query string pattern matches in RewriteRule
I'm using Isapi Rewrite 3 (mod rewrite clone for IIS) and trying to rewrite URLs based on the query string - and then pass on part of that query string in the rewrite.
So if I enter a URL like this: /test/home.cfm?page=default&arbitraryExtraArg=123
I want that to be rewritten as: /test/index.cfm?page=home&arbitraryExtraArg=123
I have the following condition/rule:
RewriteCond %{QUERY_STRING} ^page=default(.*)$ [I]
RewriteRule ^/test/home.cfm$ /test/index.cfm?page=home%1 [I,R=301]
But the extra query string variables are never passed. %1 seems to be blank.
This is how to reference a pattern match from the RewriteCond, right?
What am I missing here?
Thanks!
EDIT: It looks to me like the RewriteCond is being totally ignored. Here is what my logfile looks like:
[snip] (2) init rewrite engine with requested uri /test/home.cfm?page=default
[snip] (1) Htaccess process request C:\Inetpub\wwwroot\dev\IsapiRewrite\httpd.conf
[snip] (3) applying pattern '^/test/home\.cfm$' to uri '/test/home.cfm'
[snip] (1) escaping /test/index.cfm?page=home
[snip] (2) explicitly forcing redirect with http://www.devsite.com/test/index.cfm?page=home
[snip] (2) internal redirect with /test/home.cfm?page=default [INTERNAL REDIRECT]
[snip] (2) init rewrite engine with requested uri /test/index.cfm?page=home
[snip] (1) Htaccess process request C:\Inetpub\wwwroot\dev\IsapiRewrite\httpd.conf
[snip] (3) applying pattern '^/test/home\.cfm$' to uri '/test/index.cfm'
Should there be mention of the RewriteCond pattern check in there?

But the extra query string variables are never passed. %1 seems to be blank.
%1 is blank because according to the log the request you make is /test/home.cfm?page=default - without second parameter.
The absense of RewriteCond processing in the log may be due to low RewriteLogLevel.
And the config should be:
RewriteCond %{QUERY_STRING} ^page=default(.+)$ [NC]
RewriteRule ^/test/home.cfm$ /test/index.cfm?page=home%1 [NC,R=301,L]
