F5 LTM open connection

Hi,

Currently we are load balancing our public portal using F5 LTM. We use client ssl offload. Based on the F5 LTM connection status, I can see 6 connections are made for single login process. Can any one help to explain why F5 LTM showing total 6 connection for single login? . 

[sh@f501:Active:In Sync] ~  tmsh show sys conn cs-client-addr 139.60.XXX.XXX

    The 139.60.XXX.XXX can be a proxy/NAT device with multiple devices behind it or just one of those browser quirks/feature/bug where the browser can open up multiple TCP sessions in order retrieve information faster.
