Late response from CSM for TCP SYN_ACK

Hi

I have configured CSM to redirect one of our website to different URL. It works fine for 3 - 4 time and after that it stops working. When I check on our internet facing firewall, noticed that getting an error message saying

"First packet isn't syn tcp_flags:syn-ack"

When I did google and noticied that CSM takes time to reply for SYN request. That is the reason firewall block that traffic due to time out.
