http.readyState

I have this script right

with ajax

works perfectly in firefox and doesn't work at all in IE

I catch the data from the script using

function handleResponse()
{

alert("readystate: "+http.readyState)

if(http.readyState == 4)
{
//bla bla bla
}

}

now on ie http.ready state is always 1 it never goes past it.
what can the problem be?

Can you post more code or a link to the page?
