Hello,

Inspired by this post, I created the following Apache vhost to be able  
to run Rails and, inside /app/public, the PHP posh app.

\<VirtualHost \*:80\>  
ServerName [dev.example.com](http://dev.example.com)  
DocumentRoot “/home/www/projets.example.com/projets/  
portfolio\_immigrants/public”

```
SuexecUserGroup examplewww examplewww
ScriptAlias /fast-cgi/ /home/www/projets.example.com/cgi-bin2/

<Directory "/home/www/projets.example.com/projets/

```

portfolio\_immigrants/public"\>  
Options FollowSymLinks  
AllowOverride None  
Order allow,deny  
Allow from all  
  
\<Proxy balancer://dev\_example\_com\_cluster\>  
BalancerMember [http://127.0.0.1:6080](http://127.0.0.1:6080)  
# BalancerMember [http://127.0.0.1:6081](http://127.0.0.1:6081)  
# BalancerMember [http://127.0.0.1:6082](http://127.0.0.1:6082)

```
ProxyPass /fast-cgi !
ProxyPass /posh !

RewriteEngine On

I’m running on the server FreeBSD, Apache2, FastCGI, SuExec, Rails  
2.0.2 and Mongrel.

The problem is that I can’t find a way to makes mod\_rewrite ignore  
the /fast-cgi/ ScriptAlias. Thus, when looking at the mod\_rewrite log,  
I see the following:

init rewrite engine with requested uri /fast-cgi/php5.fcgi/posh/  
index.php  
applying pattern ‘^(.+[^/])$’ to uri ‘/fast-cgi/php5.fcgi/posh/  
index.php’  
applying pattern ‘^(.\*)$’ to uri ‘/fast-cgi/php5.fcgi/posh/index.php’  
rewrite ‘/fast-cgi/php5.fcgi/posh/index.php’ → ‘/fast-cgi/php5.fcgi/  
posh/index.php’  
local path result: /fast-cgi/php5.fcgi/posh/index.php  
prefixed with document\_root to /home/www/projets.example.com/projets/  
portfolio\_immigrants/public/fast-cgi/php5.fcgi/posh/index.php  
go-ahead with /home/www/projets.example.com/projets/  
portfolio\_immigrants/public/fast-cgi/php5.fcgi/posh/index.php [OK]

I have tried with ProxyPass /fast-cgi ! with no success. The Rails app  
works fine.

TIA

Ok, I finally figured out the solution.

Simply add this rule at the top of the mod\_rewrite rules.

RewriteCond %{REQUEST\_URI} ^/fast-cgi/  
RewriteRule ^(.\*)$ $1 [QSA,L,PT]

QSA = query string append  
L = stop processing after this rule  
PT = passthrough, let ScriptAlias handle the request
