The RHEO procedure is a specific method of apheresis - a treatment in which a patient's blood is drawn outside the body and specific compounds are removed before being returned to the body.

This site's target audience is middle aged+ individuals with vision problems, so the key feature of this site is the text size toggle that not only updates the html text but also certain flash elements. This is all done through css, javascript, cookies, and shared objects. The cookies and shared objects remember the text size from page to page and from session to session.

The site also has an advanced flash detect script that determines what the cold fusion page will serve up and stores the value on the server side ensuring only the appropriate content is delivered saving on bandwidth useage.
