Hi,

I’m currently using request.env[‘REMOTE\_HOST’] to pull back the remote  
users IP address. This worked fine in development (and production) under  
Webrick but when I tried to use it with mongrel, it kicked back an  
error.

Is there a more appropriate way to find out the remote users IP address?

Thanks in advance!
