I debugged the response header with LiveHTTPHeaders under firefox, I got header
Code:
HTTP/1.x 200 OK
Server: LiteSpeed
Date: Wed, 08 Mar 2006 17:46:34 GMT
Content-Length: 2455
Other headers were missing, like "Content-Type" and "Transfer-Encoding". Maybe you were not using the latest lsphp binary built with the latest LiteSpeed PHP SAPI, you can try the lsphp 4.4.2 binary from our package under lsws/admin/fcgi-bin/admin_php. just make sure other PHP extensions match the PHP version.
Also you can try a older version of LSWS like 2.1.9 if you still have it. I want to make sure it is not a bug introduced in the new LSWS release.
