Access Cookie Value

I have the following scenario.

  1. Display simple form which requests a user to input an e-mail address.

  2. Upon submit I create a cookie that stores the e-mail address and then directs the user to a short registration form.

  3. On the registration form I can access the cookie created in step 2 via http_cookie field. No problem.

4)Once the registration form is completed the user is directed to a view of documents. The documents contain attachments which the user may download.

Whenever one of these documents is opened I need to get the value of the cookie set in step 2 above. I cant seem to access it no matter what I try, Any ideas?

The client does not want users to have to register on the site so I dont have any user name I can get from session.DocumentContext and the cookie value is not there either.

thanks,
