apache mod_rewrite <directory> precedence over <location> with svn and trac

Question

I have an apache config file,

<VirtualHost *:443 >

    SSLEngine on
    SSLCertificateFile ...
    SSLCertificateKeyFile ...
    SSLCertificateChainFile ...
    SSLCACertificateFile ...


    ServerName www.etebaran.com

    ScriptAlias /cgi-bin/ /home/etebaran/domains/etebaran.com/public_html/cgi-bin/

        suPHP_Engine ON
        suPHP_UserGroup etebaran etebaran
    </Directory>
</VirtualHost>

The problem is, <Directory> has precedences over <Location>, so the rewrite rule on directory overrides locations.

Oddly, etebaran.com/svn still works, but etebaran.com/trac is handled by the directory directive and the PHP framework lying there.

I know there are nasty workaround, but what's the neatest one?

Answer 1

The issue seems to be your RewriteCond line. Your match pattern is ^(.*), which will match essentially anything. Use a more detailed match pattern to ensure that it won't match the URLs of your other tools. For example, a pattern of !^/svn/.* should match any URL that doesn't start with "/svn/".

Your Subversion and Trac installations seem to use URLs that start with "/svn/" and "/trac/", respectively. What do the URLs for your PHP framework look like? Do they start with a prefix as well, or are they served from the root of the site?
