Oops, sorry, missed one small issue: The rewriting engine is applied to the 
rewritten internal path again. So, if a request for /foo is received, it 
rewrites to /web/foo and applies the rules again (until they no longer apply). 
If /path/to/server/root/web/foo does not exists, the rule applies again,  so 
it's reqritten to /web/web/foo, which will again be rewritten and so on. 
The solution is to check whether the request is already for /web/.* and in 
that case don't apply the rule.

Here's the updated snippet for the .htaccess file:

###########################################

## Rewrite all non-existing files at toplevel to the /web/ dir, so our 
## internal structure for rsync doesn't have to be changed.
RewriteEngine on
RewriteBase /

# Don't rewrite already rewritten pathes!
RewriteCond %{REQUEST_URI} !^/web/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /web/$1 [QSA,L]

###########################################

Cheers,
Reinhold
