How do i check if the page has pending AJAX or HTTP GET/POST requests? I use javascript and/or python for this checking. 
what i wanted to do is execute a script if a page has finished all requests. onload doesn't work for me, if you used firebugs net panel, you would know. onload fires when the page is loaded but there is a possibility that there are still pending request hanging around somewhere.
thank you in advance.
You would need to keep track of each XMLHttpRequest and monitor whether it completes or the asynchronous callback is executed.
