[Zope] strange request

Im investigating a Zope installation that just hung for a while, and looking through the log I found this very strange request: 2001-08-31 01:26:29 151.197.229.183 - 192.168.2.165 80 Content-type: application/x-www-form-urlencoded - 404 265 - None - 0.015000 ie the and cs-method cs-uri-stem were: Content-type: application/x-www-form-urlencoded instead of for example: GET /manage Ughh. Im not sure if this caused the hang, but I was curious if anyone else has seen this...? Cheers. -- Andy McKay.
