Set-Cookie: Wildcard “Path”

Question

Is it possible to place a wildcard infront of the "path" parameter in a HTTP Set-Cookie request?

example:

Set-Cookie: SSID=foo; Domain=.foo.com; Path=/*/Stuff; Secure; HttpOnly

Answer 1

Check RFC 6265 HTTP State Management Mechanism, 5.1.4. Paths and Path-Match:

 A request-path path-matches a given cookie-path if at least one of
   the following conditions holds:

   o  The cookie-path and the request-path are identical.

   o  The cookie-path is a prefix of the request-path, and the last
      character of the cookie-path is %x2F ("/").

   o  The cookie-path is a prefix of the request-path, and the first
      character of the request-path that is not included in the cookie-
      path is a %x2F ("/") character.

It does not mention any wildcard handling, so it's not possible to use wildcards in the path.
