As a direct marketer I often find myself in the position where we need to pass data from one page to the next. The problem is with many vendors they do not allow you direct access to the source code for dynamic pages. The workaround that we have used for many clients is to pass variables from page to page using the query string (URL) and JavaScript.
I’ve included a code snippet that makes this easy and some examples of how you can use the data once passed.
