Nginx Problem with fastcgi_param

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., 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?



fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx;
fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;
fastcgi_param  SCRIPT_FILENAME    $script_filename;
fastcgi_param  SCRIPT_NAME        $script_name;
fastcgi_param  REQUEST_URI        $uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;
fastcgi_param  HTTP_HOST;
