I recently moved several websites to a new server running IIS 6 and then ran W3's link checker on the sites and it gave me the following on every page:
The link is forbidden! This needs fixing. Usual suspects: a missing index.html or Overview.html, or a missing ACL.
Checking the IIS logs I see this:
2009-10-16 15:08:13 W3SVC156278702 192.168.100.17 HEAD /west/west.shtml - 80 - 18.104.22.168 W3C-checklink/4.5+[4.160]+libwww-perl/5.823 403 1 0
The pages giving these errors are all working properly with GET, and display properly within a browser, but I'm worried that these HEAD requests being denied may cause problems with spiders. What can I do?
