Expand respond hold time

Hello together,

 

i have a standard ltm service which provides a https website. If the user request a big report the response of the backend server could take up to 30 minutes. If the F5 get's after 5 minutes no answer the f5 send the request to the backend again.

 

Where can I increase the time?

 

Best regards Johannes

    Hi Johannes,

     

    I highly doubt that your F5 will resend the ongoing HTTP request to your pool members. Its more likely that the F5 ends an idle TCP connection (e.g. Idle Timeout of the default tcp profile is 300 seconds), and the browser automatically sends a retry in the background.

     

    You could try slightly longer "Idle Timeouts" (recommended) or alternatively use "Keep Alive Interval" settings with a value lower than "Idle Timeouts" setting (use this with caution, it will keep the connection alive as long as the client is reachable).

     

    Cheers, Kai
