MVC :: Cookies Don't Work Second Time In IE 8?

I have a page on which there is a parent organisation followed by a list of child organisations. To view the data of these child organisations, there is a GO button for each child organisation. I set the ID of the child organisation in a cookie on the click of the GO button. When I come back to the home page, I delete the cookie.

My problem is that in IE 8 the first time the GO button works fine. But when I come back to the home page and click on the GO button of the same child organisation, the ID is not set in the cookie.

This problem does not occur in Firefox at all.

This is the code in JavaScript where I set the cookie and then call my page.

function GetOrganisation(id, path) {
$.get('<%=Url.Action("SetOrganisationID", "AdminSettings") %>', { 'Organisationid': id }, function (data) {
if (data.Success) {
$.get('<%=Url.Action("GetOrganisationDetails", "AdminSettings") %>', { 'Organisationid': id });

[Code]....
