As of now, the interface ClientRequestContext only allows to set a HTTP header. Sometimes it is necessary to know whether a certain header is already set in the request, so that the handler can proceed depending on whether the header is set and how.
So please provide a method to find out the value of a particular header. Maybe it would be good to also allow to find out which headers are set (e.g. return their names), but this is debatable.
