That's a very interesting idea.  Maybe it should be more specific, like
openRedirectedLocation?  That said, if one still has to call .send()
afterwards, then we are still leaving it up to the caller to pass the right
value to .send().  They have to know when the method is being changed from
POST to GET and take appropriate action.  That is a bit unfortunate.  Maybe
.send() and .openPreserveState() could just be combined into a single
.followRedirect() method?

I don't have strong opinions about that.  It is up to you.  I think it is OK
to iterate :)
