How can I exclude a directory from an .htaccess 301 rewrite on a domain?

I've spent the last h开发者_StackOverflowour trying to read, learn and figure this out myself but didn't get very far so I figured I would see if any of you might know the answer to this.

I basically have a 301 redirect on one of my domains (firstdomain.com) that points all requests to my other domain (seconddomain.com).

Easy enough, but now I have added a SVN repository onto firstdomain.com/svn. But because all requests sent to firstdomain.com are being redirected I need to find a way to exclude the 301 redirect if the URL looks for the /svn/ subfolder.

How can I make this happen?

Thanks for taking a look.

Untested, but something to the effect of the following (in firstdomain.com's .htaccess):

RewriteEngine On

RewriteCond %{REQUEST_URI} ^/svn.*$ [NC]
RewriteRule . - [L]

Redirect 301 / http://www.seconddomain.com/

In theory (something that usually takes a lot of tinkering with htacess) this should stop rewrite rules for any svn requests, but those that dont match the svn condition will be redirected 301.
