from bug 355181: Comment #23 benc@meer.net 2008-07-24 12:43:48 PDT My code-reading skills are modest, so I'll ask rather than risk an invalid bug. I was playing with some ad hoc testing of this function and I found that something like: www.host\.com fails with "hostname not found" error page. I *think* it's because this function is used like this: http://mxr.mozilla.org/seamonkey/source/netwerk/dns/src/nsHostResolver.cpp 417 // ensure that we are working with a valid hostname before proceeding. see 418 // bug 304904 for details. 419 if (!net_IsValidHostName(nsDependentCString(host))) 420 return NS_ERROR_UNKNOWN_HOST; Should we have a different error conditions for illegal/invalid hostnames? Comment #24 [reply] Jesse Ruderman 2008-07-24 13:31:49 PDT benc, I think you're right. The "Try Again" button isn't very useful in that situation either. Can you file a new bug?

I think benc is right too. Its a shame that this problem is still there.
