I am using ajax in my site. When a user enters a query and selects a category, I update the page with server fetched content using ajax. In addition I update the URL with a hash value which shows the query and the category separated by a &.
What I want to do is to make it so when the browser back-button is pressed I want to display the previous result without reloading.
What I am getting is that URL that has the previous values, but the result is not updating. How can I change that? Can any one help me?
The short answer would be use the #hash part of the uri, this part if updated doesn't refresh the page, and in most browsers makes a history checkpoint, however by saying in most browsers, means that no support in IE6, and I think IE7.
The other way is when you detect IE, you can embed a 1 pixel iframe and set it's source to a page on your domain, and make your javascript sets its ? part of the url so the page refreshes, and in this case IE will save history point.
This problem is solved in IE8
