Coldfusion 8 Cookies disappearing mid-session with IE8

I am dealing with a ticketing system that was written about 10 years ago using Coldfusion 8. When a user is authenticated and logins, the user's information about his ID is saved in CF cookies, and the site uses those cookies to fill it the user's ID, name, etc. when the user is filling out tickets.

This application works fine in Internet Explorer 6.0 However we are slowly migrating to Internet Explorer 8, so there are some users here that already started using IE8 fulltime. We've been getting complaints from some of these IE8 users, in which mid-session, the cookies are lost/become null, and the user can't complete the tickets. Users are able to login just fine, but sometimes in mid-session, errors like "NAME UNDEFINED" appear. They don't seem to be isolated to particular tickets because I've looked at all the complaints we have, and they're discovered in all sorts of tickets. I check the logs/screenshots and sure enough, the cookie for the employee ID is null. I've searched all over the web and I can't find good fixes for this.

I thought about converting cookies to session variables, but that would be a massive undertaking and require a lot of testing.

Any thoughts? Thanks in advance.

Any chance the domain is changing? You could be switching between www.servername.com and servername.com? Unless you were writing domain cookies a change in the domain would cause the written for one domain cookies to be unaccessible from another. You can enable domain cookies in your Application.cfm or Application.cfc file. Either set <cfset this.setDomainCookies = true /> in Application.cfc or set the setDomainCookies="true" attribute on your <cfapplication /> tag. This will write cookies accessible from any subdomain.

Have the cookies expired? You can set an expiration date for the cookie. Perhaps it is expiring before the user's session expires?

Have you tried using the IE development toolbar to track the cookies? You can use it to view cookies set for your site.
