The two default workers have a fixed configuration and will be used if no other worker matches the request. They do not use HTTP Keep-Alive or connection reuse. The TCP connections to the origin server will instead be opened and closed for each request. Explicitly configured workers are identified by their URL.

e HTTP persistent connection, also called HTTP keep-alive, or HTTP connection reuse, is the idea of using a single TCP connection to send and receive multiple HTTP requests /responses, as opposed to opening a new connection for every single request/response pair. Persist: Connection: Keep-Alive, Persist. to an origin server (but NOT to a proxy). This allows it to request a persist connection from either an HTTP/1.1 or HTTP/1.0+keepalive server without knowing in advance what the server type is. If the server supports both mechanisms, it should respond with Keep-Alive: Persist: Check your application and proxy server configurations to make sure that they support Keep-Alive. You need to pay close attention to the default behavior of HTTP libraries as well. You may also use HTTP/1.1, where Keep-Alive is implemented differently and the connections are kept open by default. Oct 27, 2015 · # Default is HTTP/1, keepalive is only enabled in HTTP/1.1 proxy_http_version 1.1; # Remove the Connection header if the client sends it, # it could be "close" to close a keepalive connection proxy_set_header Connection ""; }

Mar 14, 2014 · If a client opens 8 TCP connections and keeps each alive for 15 seconds after the last use, the client consumes 8 concurrency slots for 15 seconds. If clients arrive at your website at the rate of 1 per second, 120 concurrency slots are continually occupied by idle keepalive connections. Therefore, Negotiate authentication cannot be used if an intervening proxy does not support keep-alive connections. Negotiate authentication also fails if WinHttpSetOption is used with the WINHTTP_DISABLE_KEEP_ALIVE flag that disables keep-alive semantics. The Negotiate authentication scheme is sometimes called Integrated Windows authentication. Nov 14, 2014 · I tried everything including what you and someone else said to do, and I also deleted the printer and reinstalled it and it's still doing it. Even though it's wireless, I have it connected directly to the PC. I don't know what else to do. It says a lot of things on the printed page, but basically it's saying to keep proxy alive (I think). Feb 06, 2017 · Keep-alive connections. Keep-alive connections allow the client and server to use the same TCP connection to send and receive multiple HTTP requests and responses. This helps avoid. 3-way handshake for new connections— a full roundtrip of latency; slow-start; Keep-alive connections are enabled by default in HTTP/1.1 while not in HTTP/1.0.

Jun 30, 2011 · Clients and servers sent each other this header in order to tell the other side to keep the connection opened. By default, there was no keepalive. HTTP 1.1 considers every connection to be kept alive. If one doesn’t want the connection to stay opened, the client or the server has to send the header: Connection: Close.

The effective mode that will be applied to a connection passing through a frontend and a backend can be determined by both proxy modes according to the following matrix, but in short, the modes are symmetric, keep-alive is the weakest option and force close is the strongest. Balancer Manager. One of the most unique and useful features of Apache httpd's reverse proxy is the embedded balancer-manager application. Similar to mod_status, balancer-manager displays the current working configuration and status of the enabled balancers and workers currently in use. Jul 21, 2020 · The Keep-Alive and Inactivity timeouts provide better mechanisms for managing connections. To configure HTTP Active timeouts, go to Configure > Protocols > HTTP > Timeouts > Active Timeouts . For more information on configuring timeouts in the records.config, review HTTP connection timeouts (secs) in the Content Gateway Manager Help. Issue with Proxy / keep alive , getting NoHttpResponseException after a failed request. Hello, We face a bug in JMeter when : - using proxy - and using POST method which leads to a 404 - May 09, 2007 · HTTP keep-alive connections can be re-used for multiple requests, as opposed to non-keep-alive connections, which are limited to one request. Using keep-alive connections improves performance. If a proxy server is not configured, this preference controls whether to use keep alive connections on supporting servers.
