Rails - Sep 2006 - Using mod_rewrite instead of mod_alias to mask rails directory

Hi all,

I''m experiencing some google groups strangeness (namely my post from
yesterday being sent to /dev/blackhole - so apologies if this _does_
show up twice.

I''m trying to use mod_rewrite to mask the location of my rails
directory.  My virtual host set up is as follows:


/httpdocs (docroot)
/rails (railsroot)

so browsing to mydomain.com/rails/controller/action actually goes to
the railsroot directory above .  This all works beautifully (using
Apache 2 / mod_fcgid btw - which is absolutely excellent!)

What I want is for people to be able to hit
mydomain.com/controller/action.  One obvious way of achieving this is
with mod_alias, but as my site is managed with Plesk, making vhost
level conf changes is a bit tricky (and a real maintenance hassle) so
I''d prefer to accomplish this with a .htaccess level mod_rewrite rule.

What I''ve currently got is an htaccess file in httpdocs:

Options +FollowSymLinks
RewriteEngine On

RewriteCond %{REQUEST_URI} !^/rails/
RewriteRule ^(.*)$ /rails/$1 [L]

Which is fairly straightforward.  The crazy thing is that although this
successfully redirects "/" to the shortcut rails route, every other
URL
also gets directed there (eg: /news, /contact all end up at / in the
rails app.)  Full controller/action/param calls get a 404.

I''ve tried a couple of variations on this rule:

RewriteRule ^(.*)$ /rails/public/$1 [L]
RewriteRule ^(.*)$ /rails%{REQUEST_URI} [L]

Both of which exhibit the same behaviour.

The following rule results in a 404:
RewriteRule ^/(.*)$ /rails/$1 [L]

(note the addition of the / to the match)

Obvioulsy if I specificy a 30x redirect with [R] it works.  I''ve
checked the rails log, and the correct url is being called.

In an act of voodooish desperation I even tried using the RewriteBase
directive in the rails/public/.htacess.

Can anyone think of anything obvious (or even slightly less obvious)
that I''m doing wrong?

Thanks!

Corin
