If you go to the url above, and try to click on Customize, which is a relative link to Customize.shtml, you will be forwarded to http://customize.shtml. I am using a build from yesterday night. When I tried to reproduce this with a smaller test case, I could not. Needs more investigation.
The HTML in that page is broken. When I view source it, here's what I see for that link: <A href="http:customize.shtml"> For some reason NC 4.71 resolves that link correctly. Very bizarre. Why are Netscape employee's not able to set a bug as new? I feel weird confirming a Netscape employee's bug report ;-)
this is a networking bug, resolving http:url without domain name and // wrong (as jerry baker saw)
This is a dup of bug 22251, which is marked wontfix! I fact the above relative URLs are a loophole in old RFCs which are deprecated but still in use. *** This bug has been marked as a duplicate of 22251 ***
