Citrix ADC

Request retry

When a Citrix ADC appliance receives an HTTP request but has a connection failure with a back-end 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 a back-end server resets a TCP connection when an HTTP request is received. For more details, see Request retry.
  • If a back-end server resets a TCP connection during connection establishment. For more details, see Request retry.
  • If a response from a back-end server times out (based on the configured time-out value) when an appliance sends an HTTP request. For more details, see Request retry.
