[gentoo-user] [Apache HTTPD] Why doesn't my RewriteRule fire?

[Hilco Wijbenga]

Hi all,

I hope some Apache guru can help me out. I must be missing something
very obvious.

Assume a default Apache 2.2.17 with all modules installed and -D PROXY
-D INFO in /etc/conf.d/apache2.

My update to the default VHOST:

ForensicLog       /var/log/apache2/forensic.log
ProxyRequests     off
RewriteEngine     on
RewriteLogLevel   9
RewriteLog        /var/log/apache2/rewrite.log
<VirtualHost *:80>
  ServerName localhost
  ServerAdmin root@localhost
  DocumentRoot "/var/www/localhost/htdocs"
  <Directory "/var/www/localhost/htdocs">
    Options Indexes FollowSymLinks
    AllowOverride All
    Order deny,allow
    Deny from all
    Allow from 127.0.0.1
  </Directory>
  RewriteRule ^/website$    http://localhost/website/ [T]
  ProxyPassMatch    ^/website/(.*)$
http://localhost:8000/website/$1
</VirtualHost>

The ProxyPassMatch fires but (AFAICT) the RewriteRule does not. I.e.
http://localhost/website (no slash) ==> 404 (in fact, it's trying to
serve /var/www/localhost/htdocs/website) but http://localhost/website
(with slash) ==> works.

Why does the RewriteRule not run? FYI, rewrite.log is created but
stays empty. I don't see any errors or warnings in access.log or
error.log.

Cheers,
Hilco

You have [T] as third parameter to RewriteRule, which is used to
specify a MIME type,  but you're not specifying anything. Maybe that
invalidates the rule. Try removing it.

You can also specify multiple RewriteRules which are processed in
sequence, if trailing slash works maybe you need to first add a rule
convert URL with no slash to URL with slash:

RewriteRule ^/website$ /website/ [R]

Well, you know more than I do. :-)

I used to have [P] and then tried [PT] but neither worked. Then for
some unknown reason I deleted the P and left [T] when I sent the
email.

The problem turns out to be that you must put the Rewrite*
configuration stuff in the virtual host, not outside. Then it works.
It's documented but I had glossed over it.
