I have a client application that uses WebHttpRequest to get response from external server, it works fine but some times I'm getting the following exception ....

System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond xx.xx.xxx.xxx:xxx at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.InternalConnect(EndPoint remoteEP) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Int32 timeout, Exception& exception) --- End of inner exception stack trace ---

at System.Net.HttpWebRequest.GetRequestStream(TransportContext& context)

at System.Net.HttpWebRequest.GetRequestStream()

.... Any help?

This is more of a "Request Timed Out" error. The server you are trying to connect to did not respond to your request. You should handle this exception using try-catch and attempt to connect n number of times again in the catch block.
