i tried to install google friend connect on my forum, and i can't get it worked.
when i checked with firebug, it shows:

""NetworkError: 400 Bad Request - http://mc8tdi0ripmbpds25eboaupdulritrp6-a-fc-opensocial.googleusercontent.com/ps/ifr?container=friendconnect&mid=0&nocache=0&view=profile&parent=http%3A%2F%2Fwww.ceriwis.us%2Fhanyates%2Fvbnexus%2Fgoogle%2F&url=http%3A%2F%2Fwww.google.com%2Ffriendconnect%2Fgadgets%2Fosapi-0.8.xml&communityId=11096874856524462449&caller=http%3A%2F%2Fwww.ceriwis.us%2Fhanyates%2Findex.php&rpctoken=273046583""

but when i installed the plugin on apache it works.. anybody knows what is the problem above ?
im googling it and find "http://forum.nginx.org/read.php?2,61022,61178"
and i've added "large_client_header_buffers 4 8k;" to the config files but it still show the same error..

maybe people here knows what really happen and how to solve it.
any help will be appreciated. Thanks
