HTTP: retry technical questions

Hello, I am reading the wiki article for HTTP: retry where I have few questions on "Re-sends a request to a server. Can be either the same or a different request, to the same or a different server."...

Thank you for your reply and providing the insights. Please address my follow up question.

  • "if you want to interfere with the pool member selection you will need to code it in the iRules" So May I know if the service will be skipped (removed from the pool) if it is sending the 5xx error
  • I want to know what will happen to the service which has sent the 5xx error, will that remains in the server pool or will it be removed from the pool for some interval so that next request should not select this service. I am referring to LB:FAILED event (https://devcentral.f5.com/s/feed/0D51T00006i7ZpISAU)

Thank you   for your response, As I can see LB:FAILED event takes out the server from the pool so can I use this event along with HTTP retry event.

I want to make sure if responding server is sending 5xx error, then that server will be out of server pool for some time and then monitor will prob it once server is sending desired response we will add it to server pool again.

Will that be possible?
