There is one subtlety however: since the "Upgrade" is a hop-by-hop header, it is not passed from a client to proxied server. In my case, setting a time-out on the socket would help and make the application more robust but I don't think it fixes the problem entirely. These properties specify the default connect and read timeout (resp. SocketTimeoutException. To make sure all requests will be sent out correctly, we recommend to use the PluginClient with the following plugins:. SocketTimeoutException: timeout. To configure any of them, a custom http. It is sent on an idle connection by some servers, even without any previous request by the client. The transport module is used for internal communication between nodes within the cluster. Timeout includes all time spent following redirects, while the granular timeouts are specific for each request, since http. The basic request-reply pattern (a REQ client socket doing a blocking send/receive to a REP server socket) scores low on handling the most common types of failure. 0, it was assumed that a connection was done as soon as client had asked for a thing and the server had finished sending it; the server then closed the connecti.

Requests and keepalive connections can only be idle for a limited time before Resin closes them. The transport module is used for internal communication between nodes within the cluster. A very nice trick! In C I usually create a blocking socket class that implements blocking socket functions like connect/send/recv but inside the implementation uses nonblocking socket and some kind of waiting operation (select/WSAWaitForMultipleEvents) and it waits for the socket plus an event object (usually a pipe on linux/select). Socket Client The following C# example demonstrates how to send SCPI commands to the PNA via a TCP socket connection and how to use a TCP 'control' connection. msg123288 - Author: Antoine Pitrou (pitrou) * Date: 2010-12-03 20:00; Committed in r86997. io or Primus connection directly without Feathers on the client side.
