Hi I did a test today and it looks like co-op crawler does not follow 301 redirections and thus fails to validate a site which them. I have a site under free subdomain alias, which i failed to validate because my free subdomain points to IP of that free subdomain service server which then does 302 redirection to my site. There is also another free subdomain service which works quite similar to what i've described above, but instead of 302 redirection, it uses iframe tag to display content of target site. Does coop crawler follows iframe tags ? Greetings and Happy New Year! Greg
