GetCookieHeader returns a string that holds the HTTP cookie header for the Cookie instances specified by uri. The HTTP header is built by adding a string representation of each Cookie associated with uri. Note that the exact format of the string depends on the RFC that the Cookie conforms to. The strings for all the Cookie instances that are associated with uri are combined and delimited by semicolons.
