Citrix ADC

Request retry

When a Citrix ADC appliance receives an HTTP request but has a connection failure with backend server, the appliance uses a retry directive. The request retry addresses connection failure scenarios and enables the appliance to choose the next available service and forward the request. By doing a request retry, the client can save round trip time (RTT).

Request retry feature is applicable for the following connection failure scenarios:

  • If back-end server resets a TCP connection when an HTTP request is received.
  • If back-end server resets a TCP connection during connection establishment.
  • If response from back-end server times out (based on the configured time out value) when appliance sends an HTTP request.
