This is exactly what it sounds like: somebody tried to get information from your website, but the request was so munged that the server couldn't respond properly. It's probably nothing to worry about, but could indicate an attempted buffer-overrun attack or something similar. > ERROR CODE 405: METHOD NOT ALLOWED > The method specified in the Request-Line is not allowed for the resource > identified by the Request-URI. The response MUST include an Allow header > containing a list of valid methods for the requested resource. > Would this mean your are using a form method other than POST and GET? Probably. Again it's probably a fishing attack checking for weaknesses in your config. "POST" and "GET" are the most common method types, but there are others - the nasty one is "PUT" which allows the remote request to create data on your server. No server I know of ever leaves that method open, but if it were somebody could easily place information on your server and point others to it for downloading (when FTP servers are leveraged this way it's called "[EMAIL PROTECTED]" them). It might also just mean that the method passed was munged and didn't mean anything (the method specified must be specifically allowed - random strings will cause such an error). This might also happen if the resource the request was ultimately directed to didn't accept a method. We've seen this problem with WebSphere and Structs were the class being redirected to wasn't configured to handle "GET" but could handle "POST". If a GET was sent you'd get this error.
