<b>What does it do?</b>
This function uses three js files called PopoffWindow, GetBrowserOSVersion, and CanSetCookies to check whether the browser is netscape or ie (or if it is just a mac using ie), whether it is under version 5, whether we have not done a redirect for this browser in the last 10 years.  If all of that is true, it then a pop off gives the user some upgrade info.

<b>How do I use it?</b>
(place the JS files somewhere on the page and put the function call RedirectOldBrowsers anywhere underneath the JS file call)

&lt;script src="/js/standardFunctionality/PopoffWindow.js"&gt;&lt;/script&gt;
&lt;script src="/js/standardFunctionality/GetBrowserOSVersion.js"&gt;&lt;/script&gt;
&lt;script src="/js/standardFunctionality/CanSetCookies.js"&gt;&lt;/script&gt;
&lt;script src="/js/standardFunctionality/STSpecific/RedirectOldBrowsers.js"&gt;&lt;/script&gt; 
&lt;script&gt;RedirectOldBrowsers();&lt;/script&gt;
