Browser threads and Ajax

Internet Explorer Web Development

RickMur

Hello Guys:

As I recall, IE 6 browser supports 2 threads. Somehow I just could not find this info anywhere on my google search :=( bad search creteria or what ) . Basically I am also trying to find that info for FireFox as well. Any body can share more info on the browser thread info

What I am trying to understand is that because javascript does not support threading by itself and how browser thread plays a role in Ajax calls Since async calls are all fire and forget, Does that mean, each thread, say in IE situation, is responsible for one XMLHttpRequest and once the async call comes back and frees up that thread, another call can be made. In another words, maximumly, only two active calls can be made each time from IE browser in an Ajax app. Is this is fair statement to say

Thank you all.

IE will only keep open 2 HTTP(s) connections to the *same* server at once... so if you are downloading 2 large scripts, everything else queues up.

Firefox realized this "old" standard was outdated (now that most have broadband) and increased it... (I think 8 or 16 )

The IE team has also indicated that in IE8, they too will increase it but choosed not to in IE7 (althought RSS connections in the Feeds section will be counted seperately)

If you want to improve the speed of IE, there are extensions that will up the 2 to 10 or some other value.

Thank you for answering my question. Could you give some pointers to what those IE extensions are and where I can get those extentions Also, how does these 2 IE threads (2 Http connections) play a role in an Ajax application or they play any role at all

Thank you.
