2-application Symfony 1.4 ROUTING

I do have two application, e.g. "frontend" and "b2b". Frontend is my main application for users. b2b is then of course for business-customers. When I am going to type

www.myhomepage.com -> My routing goes to something like frontend/module/start/index.php

When I am going to type:

www.myhomepage.com/b2b.php/ -> My routing goes to something like b2b/module/b2bstart/index.php开发者_如何转开发

How can I set the routing that when I type

www.myhomepage.com/b2b that I got to b2b/module/b2bstart/index.php???

TIA!

PS: Using symofony 1.4

A way could be to use a rule inside the file .htaccess:

RewriteRule ^b2b myproject/web/b2b.php [NC,L]

I used this type of rule, positioned after RewriteEngine On, in the file .htaccess outside to my project folder
