// attempting to do the dereferencing or delivery. Any authentication

// The gofedAgent passed in should be used by the Transport
|
|
// implementation in the User-Agent, as well as the application-specific

// user agent string. The gofedAgent will indicate this library's use as
|
|
// well as the library's version number.
