We might now suspect that our first requests are blocking subsequent ones, but why? Instead, use the System.Net.Http.HttpClient class. cases. The time allotted to this operation may have been a portion of a longer timeout.

Once located, open nginx.conf in a text editor and look for client_body_timeout, client_header_timeout, or keepalive_timeout directives, which are all part of the http_core Nginx module. The following lines will demonstrate how to accomplish that task. These are the top rated real world C# (CSharp) examples of System.Net.HttpWebRequest extracted from open source projects. My question is, how could I detect that the connection to the server has been lost in the middle of a download with UnityWebRequest? You can rate examples to help us improve the quality of examples. Dim objStream As System.IO.Stream Dim objReader As System.IO.StreamReader Dim objRequest As System.Net.HttpWebRequest Dim objResponse As System.Net.WebResponse Try objRequest = CType(System.Net.WebRequest.Create(sbURL.ToString), System.Net.HttpWebRequest) objRequest.Timeout = TimeOutInMilliseconds 'Fixes tried 1..no luck objRequest.KeepAlive . webRequest.set_Timeout(5000); //setting encoding.

The timeout is handled by running the asynchronous operation inside an other task. The actual behavior of WebRequest instances at run time is determined by the descendant class returned by the WebRequest.Create method. For more information about default values and exceptions, see the documentation . for user management scripts), run your jobs more frequently so that each individual job is small. If the resource is not returned within the time-out period, the request throws a WebException with the Status property set to Timeout.
