FAQ Topic - Why is my Ajax page not updated properly when
using an HTTP GET request in Internet Explorer?
-----------------------------------------------------------------------

Browsers cache the results of HTTP requests to reduce network traffic.
To force the browser to request the document from the server, either
set the ` EXPIRES ` and/or ` CACHE-CONTROL ` response header(s)
with a past date or use a unique query string.

req.open("GET", "/example.jsp?date=" + (+new Date), true);

Always use the appropriate HTTP method. Do not use ` POST `
to prevent caching. See
