LB::detach

Is there any reason to use the LB::detach event only in event of LB_failed.

What is the consequence if i use the LB::detach for every http request. We have a virtual server with http,tcp, ssl client, cookie persistence profile assigned and we want to assign an irule to detach server connection since we are using http pipelining and as per recommendation in SOL7964. Pls suggest

rule persist-cookie-keepalive {

Now we want to use like below:

rule persist-cookie-keepalive {
