Return Value

An HTTP cookie header, with strings representing Cookie instances delimited by semicolons.


uri is a null reference (Nothing in Visual Basic).

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.

This string is not in the correct format for use as the second parameter of the SetCookies method.
