Re: how does request.host get set?

Thanks for the hints. I'm using apache & mongrel. I think I found
where it gets set, in the cgi_process.rb, apparently
env["HTTP_X_FORWARDED_HOST"] is used to get the host, in my case there
are 2 values, the public and the private address, it happens to take
the latter. now I need to find where HTTP_X_FORWARDED_HOST gets set.
it seems that it should be apache conf thing right?
