Hello everyone
Perhaps you have seen the loading message at the top of the gmail page you can see if you try and visit this site in every place you click inside the gmail boxs or sending message to others the yellow message appears at the top and it works fastly I can say faster than yahoo mail and others because it works incredibly fast even when you use dial-up internet connection by low-bandwidth.
I am intended to know what is going on behind the sense and what method they used to increase speed I've known some technology like ajax and some methods but I can't implement all with ajax for example I can't remove all of the postbacks but they did it.
Is anyone who knows something about google and it's infrastructure ?
