Add delay before sending each packet of HTTP response back

Thanks for your help !

 

 

Sorry I didn't tell the situation clearly and entirely. Actually not all of clients have poor performance problem, just some of them which I can use HTTP header to identify them. Even the rate is limited from those clients with poor performance, it doesn't help. I found if I can slow down the response, the situation can be improved. However, I don't want to slow down the response for all of clients, so I would like to use iRule to add delay just for those clients which performed badly.

 

 

Could you tell me in which event I can add loop ? It seems that event of HTTP_RESPONSE is triggered only for the first packet of HTTP response, not all of packets (response body).
