Thanks for all your replies i was using IE because of that issue and it was damn slow to open this sites. Today my problem is resolved. Actually it was the problem with my proxy and it was given a proxy. When i removed the proxy, it started loading & running websites. Thanks for all your answers and those both links were very useful.
