Why AJAX is fast ????

[dmjpro]

i think u know AJAX .......

let me clear a typical thing ..... that why AJAX is fast?
does AJAX use any other communication channel as contrast to the normal request does... or the same communication channel ?

i think u got my point what i mean.....

plz clearify me ...... thanxxxx

Ajax is no faster than any other HTTP transactions.  It simply appears faster because it avoids the need to reload an entire page - you simply load in the particular data you need, and leave the rest of the web page intact.  (That's typically how Ajax is used.)

ok kkkkkk i also knew that ... but i just waiting for an expert

Ajax does have the advantage of being able to pass any kind of XML (or text) data you like, so with a bit of cunning I suppose you could compress your data and make transmission swifter...

The whole thing is XML at both ends by definition.  You might find >this< illuminating.

No, no: the browser sends the form data.  Use the HTML code above to do it.
