URL rewriting in PHPCloud

Found out today that the typical rewrite rule

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]

doesn’t work too well in the DevCloud.  I would get log errors like

[Tue Feb 07 13:06:33 2012] [error] [client 192.168.0.254] Request exceeded the limit of 10 internal redirects due to probable configuration error. Use ‘LimitInternalRecursion’ to increase the limit if necessary. Use ‘LogLevel debug’ to get a backtrace.

Turns out that the fix is really simple.

Options +FollowSymlinks

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteBase /
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]

Adding RewriteBase fixes the problem.
