The problem I'm facing is as follows. I'm using a JSON call to check

some data before doing a JS redirect to a different page. The redirect

works but it's impossible to get back to the initial page using the

browser's back button. The initial location is not being stored in the

browser's history.

This is the script simplified. If placed on http://site1.example.com/

when it's executed it redirects to http://site2.example.com/ but

there's no way to go back to http://site1.example.com/ using the

browser's back button.

$(document).ready(function(){

$('#click').click(function(){

$.getJSON('index.php?jsoncallback=?', function(msg){

location.href='http://site2.example.com/';

});

});

})
