256869 - '\' in URL lead to page not found

Status: RESOLVED INVALID

(SeaMonkey :: General, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3

We have an intranet where the URLs have been written as \foo\bar.htm . Using IE
and Opera these links are followed ok. With Mozilla / Firefox the \ is
translated to %5C and the link is appended to the current level URL.

E.g. the framset http://mka-compaq/g4d/htm/gprsframe.htm has a link is written
as src="\G4D\htm\default_info.htm". All the frames show "Not Found". When "This
frame --> Show only this frame" is selected the following is shown in the URL
bar: http://mka-compaq/g4d/htm/%5CG4D%5Chtm%5Cdefault_info.htm, which is why it
does not work. Removing the 'g4d/htm/' gives:
http://mka-compaq/%5CG4D%5Chtm%5Cgprs_stack.htm and the page shows correctly.

(N.B. Neither http://mka-compaq%5CG4D%5Chtm%5Cgprs_stack.htm nor
http://mka-compaq\%5CG4D%5Chtm%5Cgprs_stack.htm display a page either, whereas
they do in IE.)

Mark this as a duplicate but please don't loose sight of the fact the the core 
problem in this report is that the src="\foo\bar.html" is appended to the end 
of the core URL, this is what causes the 404 - NOT the %5C.

Because Mozilla doesn't recognize the \ or %5c as path separator and therefor
doesn't know the correct base URI and appends (wrongly) the URL. See bug 254169
comment 2 etc. and Bug 236440.

Other bugs are bug 32895 comment 29, Bug 93197.

a "\" is invalid in an URL and must be escaped (Mozilla doesn that).
Opera and IE seem incoirrectly convert a "\" to a "/"

-> invalid
(Please correct the "\" in the page to "/"
