I am facing a problem in my Singapore office network that a single website is taking 2-3 minute to load the page however other sites are opening very quickly. Proxy server is there in between and users accesing site through proxy. I tried accessing site via DMZ out bypassing firewall and proxy page is opening quickly. Also if I use our US proxy result is good,problem is only with singapore proxy and only for a single website i.e http://184.108.40.206 . Even proxy authentication prompt is taking time to pop up on screen for this particular website. Connectivity is like ....
Internet route------->Firewall------> Proxy------>User in LAN
Can somebody please suggest on this.
