Question

I am experimenting with several languages (Python, Ruby…), and I would like to know if there is a way to optimize my Apache Server to load
certain modules only in certain VirtualHost, for instance:

http://myapp1 <- just with Ruby support 
http://myapp2 <- just with Python support
http://myapp3 <- just with Php support
...

Thanks.

Each Apache worker loads every module, so it’s not possible to do within Apache itself.

What you need to do is move your language modules to processes external to Apache workers.

This is done for your languages with the following modules:

• PHP: mod_fastcgi. More info: Apache+Chroot+FastCGI.
• Python: mod_wsgi in daemon mode.
• Ruby: passenger/mod_rack
