Ajax responses very slow.

22 New Member
Hi Friends,

I have a web application through which, the ajax is used to post the data onto the server and return the results. When i alert the xmlhttp.readyst ate sometimes it takes long time, that the process looks like freezing and sometimes its done very quickly as it is designed to.

I checked by alerting xmlhttp.readyst ate.

sometimes i get response 1,2 ,3 4 as the alert box quickly.
and sometimes i just get 1 and then nothing happens.

Has any one experienced the same.

maybe problem with your PHP file. Try to send the same variables to the file through a manual call (enter it in your browser address bar), it maybe that this file never gets back.

Only thing I can think of that causes this.

Just try to get the response from a dummy PHP file...

If the response time is same for every call.. then as dlite922 told its a problem with your PHP... Prpbably you need to fix some issues..

I checked that , but if i send the variables directly to the php file as the action in the form tag, it goes out fine. I am using IE 7.0 and sometimes it works fine and sometimes does not work.

Hi Dheeraj,, even firefox and ie shows the same response. and there is a javascript code written that the web application cannot be used on a firefox. can you think of something else.

Do think that multiple requests are being fired off?

If so, that may part of the bottleneck.

If I remember correctly, IE will open only 2 connections at once.

You might also want to add a timeout in your Ajax callback function so the application is more responsive.


Post your httpRequest and callback function.

that seems more to be a problem with the JavaScript-code then with the php-code. could you post the JavaScript-code that is relevant for the ajax-call?

kind regards

Hello !
