Rename the second method to something else like “Friends_Post” and then you can add [ActionName("Friends")]
attribute to the second one. So the requests to the Friend action with POST as request type, will be handled by that action.
// Get:
[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Friends()
{
// do some stuff
return View();
}
// Post:
[ActionName("Friends")]
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Friends_Post()
{
// do some stuff
return View();
}
