System crash when reading any http request

[Oldes]

The recent change of handling event/offset values in this commit: a6c966f
is causing crash when reading any url.

With quick look at it, problem may be, that http protocol is using event/offset as a hacky way to report need of redirection:

Lines 124 to 127 in cfc52b0

	if all [event/offset event/offset/x = 300][
	event/port/state/state: 'redirect
	return true
	]
