Even though backslash is not a legal URI character in HTTP/1.1 one could interpret HTTP/1.0 (RFC 1945) so that is is a legal URI character (in section 3.2.1; work your way from abs_path and rel_path through path, fsegment, segment, pchar, uchar, unreserved and then you find national. It is defined as "any OCTET excluding ALPHA, DIGIT, reserved, extra, safe, and unsafe" of which none includes backslash). It looks like Mozilla does not even try to load a URI with a backslash in it. Navigator 4.61 loads it as it is and IE 5 remap backslash to slash.

Necko landing...

I'm moving this to target M9, Necko will be enabled somewhere during late M8 or early M9. We will need to get on this and it cannot be postponed past the M9 milestone.

Changing all Networking Library/Browser bugs to Networking-Core component for Browser. Occasionally, Bugzilla will burp and cause Verified bugs to reopen when I do this in a bulk change. If this happens, I will fix. ;-)

Pl. verify with Necko.

this URL is crashing as soon as you enter it in xpcom.dll on windows 0730 builds, re-opening. Sorry no stack trace, talkback not working. Okay on linux and mac!

Fixed. will check it in tomorrow morning with other changes.

Bulk move of all Networking-Core (to be deleted component) bugs to new Networking component.

Firefox for windows does not allow backslash in urls. Checked on the lates version 24. On linux it is working fine. Example: <link rel="stylesheet" type="text/css" href="/assets/d9a519b9\style.css" /> This css will not be loaded. <link rel="stylesheet" type="text/css" href="/assets/d9a519b9/style.css" /> This is OK
