system.net.webexception

I am having problem with ftp, in a windows service. I have scheduled a job to sent files through the ftp. Once in a while i'm having timeout (frequency once a week or maybe once a month), and it continues till i restart my windows service. System.Net.WebException: The operation has timed out. I'm handling the exception and in finally i close any opened ftp sessions. try { string uri = String.Format("ftp://{0}/{1}/{2}", server, download, file); Uri serverUri = new Uri(uri); if (serverUri.Scheme != Uri.UriSchemeFtp) { return; } FtpWebRequest reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri

I'm calling a .NET 2.0 web service within my existing .NET 2.0 web service. I would like to know what exception is thrown from the web method if a timeout happens. I have set the web service timeout to some lower value than the default 90 seconds and I want to add business logic if timeout happens. Is [System.Net.WebException][1] the exception I should be looking at? This kind of depends on which "version" of web services you are using. Using WCF, you will actually get a TimeoutException . You should generally also handle CommunicationException if you are attempting to handle timeouts.

Our console applications are making hundreds of WebRequests to Facebook every minute (with using multiple apps and hundreds of access tokens). Now, they started to fail with the exception message in the title ("The request was aborted: The request was canceled"). We searched for hours on the internet, and tried out every possible solution, but nothing helped. These didn't help: webRequest.Timeout = 20000; //A request that didn't get respond within 20 seconds is unacceptable, and we would rather just retry. webRequest.KeepAlive = false; webRequest.ProtocolVersion = HttpVersion.Version10;

I've hunted around for some definitive documentation on this but haven't had much luck finding any. For which HTTP Response Status codes will HttpWebRequest.GetResponse() generate a WebException after doing something like a POST? Specifically, will it generate a WebException for anything other than status 200 OK ? Or will it only generate a WebException for say, 400, 404, and 500 (for the sake of argument)? I want to know since the server I'm communicating with defines anything other than HTTP 200 OK coming back as an error condition. Can I rely on a WebException being generated for anything
