Nginx Problem with fastcgi_param

[Erik Osterman]

We've been running Nginx(0.5.33)+FastCGI(php-cgi 5.1.6) on Fedora 6 for 
1 week now and very happy with it. Before this, we were using Nginx as 
strictly a HTTP load balancer. I have encountered an issue migrating to 
FastCGI, which is that HTTP_HOST cannot be set using fastcgi_param. It 
seems that no matter what I pass (e.g. foobar.com), Nginx is not 
honoring it, passing the real HTTP_HOST of the request instead. The 
other variables like SCRIPT_FILENAME and SCRIPT_NAME are getting set 
properly if I change them.

Is there something I am doing wrong or is this a known issue?

Best,

Erik
