Hi, we've put the cachemgr.cgi on a Microsoft IIS 6.0 server which also runs Squid for NT. By allowing "All unknown CGI extensions" and putting cachemgr.cgi as default homepage we are able to browse to this site. When we logon however we get a CGI error: The specified CGI application misbehaved by not returning a complete set of HTTP headers. When I put the cachemgr.cgi script on a IIS 5.0 then everything works perfectly. Are there any known issues with running the CGI-script on IIS 6.0? Thanks in advance for any info. Kind regards, Jeroen
