"The specified CGI application misbehaved by not returning a complete set of HTTP headers." I am using IIS6.0 and i installed activestate 5.8.8 on the server. Set the web extensions and configured the application settings of my web site. After that I also updated awstats which created the data. But when i try to view with this url: http://www.mydomain.com/awstats/cgi-bin/awstats.pl?config=mydomain It fails with that message in 2 different frames with the same message. Does anyone have similar experience with IIS and awstats? I've spent 2 days to set it up, now I can't view them Your help will be very much appreciated..
