[users@httpd] mod_rewrite: use rewrite map in RewriteCond pattern?

Is there any way to accomplish something like the following?

RewriteMap hn txt:/apache/config/hostname.map
RewriteCond %{HTTP_HOST}        ${hn:www} [NC]

Thanks!

Eric,

Thanks for the pointer, it worked like a charm.  Note to others, this doesn't appear to work with 1.3

you can't have variables of any kind in the regex, because it's only
compiled once not per-request.

You can put both the variable and the HTTP_HOST in the test string
(first parm) with some separator then make sure they're equal by using
an internal backreference instead of one fluffed up my rewrite itself:

e.g.

RewriteCond %{HTTP_HOST},${hn:www} ^([^,]+),\1
