Bug ID: 42465
           Summary: winhttp set_cookies() violates RFC6265 string
                    comparison rules
           Product: Wine
           Version: 2.0
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winhttp
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

For example, RFC6265 section 5.2.4 states:
> If the attribute-name case-insensitively matches the string "Path",
>   the user agent MUST process the cookie-av as follows.

But set_cookies() uses string "path" and performs case-sensitive comparison.
Same stuff with section 5.2.3 and string "domain".

This issue breaks cookie exchange with certain HTTP servers.

Probably there are other similar issues in Wine since HTTP string processing
should be case-insensitive in most cases. And most server implementations use
Camel-Case strings.

This issue also affects Wine versions prior to 2.0.
