			In an ideal world, we would fix it on the Network layer at a platform level.
			The problem is that all the working methods (blocking sockets, not blocking synchronous sockets
			with and without overlapped I/O, completion routine and possibly completion ports) are not suitable
			for Opera, as they require additional threads or a call to SleepEx().

			For some reasons, it looks like asynchronous sockets (both with and without overlapped I/O) are not able to cope with this problem.
			So we decided to isolate the problem and attempt a redirect.
			For example: if http://skandiabanken.no fails with a reset, http://www.skandiabanken.no is attempted.
			This fixes CORE-45283 and possibly other similar cases.
