AbstractClient - use correct method for redirected request

There is something on Wikipedia but RFC would be better.

See note here

The way I understand it from these RFCs:

301, 302, 307 - If following redirect, use previous HTTP method. (But the redirect should not be automatic if the method was POST. It may be automatic for GET and HEAD. I didn't find any mentions about other methods.)
303 - Always use GET to follow redirect.

But as it is said in the note, many clients use automatic redirect on 301 and 302 with switching to GET method.

OT: There is a suggest to use 5 redirects as limiting, maybe it should be changed here.
