FWIW I understand the backslash should be percent-encoded in URLs, otherwise the URL is not valid. This reminds me of a few other bugs: * Issue 30500: Made the behaviour of fragment (#. . .) versus userinfo (. . .@) consistent, e.g. in //www.google.com#@xxx.com * Issue 18140: Also about the ambiguity of fragment (#. . .) and query (?. . .) versus userinfo (. . .@) * Issue 23328: Precedence of path segment (/. . .) versus userinfo (. . .@); e.g. //user/name:pass/[email protected] I think people some times come up with these invalid URLs because they are trying to make a URL that includes a password with unusual characters (e.g. for the “http_proxy” environment variable). So raising an exception or otherwise changing the parsing behaviour could break those cases.
