5xx response code error Irule issue

Hi Parveez

Since you want to run all events except LB_SELECTED when the pool is pool_testprior.levi.com I guess you can test for the two before running the logic in HTTP_RESPONSE.

Then you can do something similar in the LB_SELECTED event.

Please note that "LB::reselect pool pool-test_shop.kpr.com_http" was changed to just LB::reselect and that there's no guarantee that it will choose unique servers on all attempts as it used the load balancing method.

Try this one?

when CLIENT_ACCEPTED { 
    set count 0 
}

when HTTP_REQUEST priority 800 { 
    set request [HTTP::request]
}

when LB_SELECTED { 

    if { $count >= 1 } {

        if { [LB::server pool] != "pool_testprior.levi.com" } {
            log local0. "Deleting cookie 73686f706c656e6f766f with value \"[HTTP::cookie value 73686f706c656e6f766f]\"" 
            HTTP::cookie remove "73686f706c656e6f766f" 
        }

        LB::reselect
        log local0. "Reselection: member [LB::server addr]:[LB::server port] from pool [LB::server pool]" 

    }

}

when HTTP_RESPONSE priority 800 { 

    if { [LB::server pool] == "pool-test_shop.kpr.com_http" || [LB::server pool] == "pool_testprior.levi.com"  } {
        if { [HTTP::status] eq 503 && $count < 3 } { 
            incr count
            HTTP::retry $request 
            log local0. "[HTTP::status] from [LB::server addr]:[LB::server port], trying another [LB::server pool] member (retry $count)" 
        } elseif { [HTTP::status] == 503 && $count >= 3 } { 
            HTTP::redirect "http://www.kpr.com" 
            set count 0 
            log local0. "Redirect to dotcom due to panic mode (retried pool [LB::server pool] $count times)" 
        } elseif { ! ( [HTTP::status] eq 503 ) && $count >= 1 } { 
            set count 0 
        } elseif { $count >= 1 } { 
            log local0. "Retry count = $count for pool [LB::server pool] -- this connection is being reused" 
        }
    }
}
