From: FAQ server on 6 May 2010 19:00 ----------------------------------------------------------------------- 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 reduces 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 http://www.faqs.org/rfcs/rfc2616.html http://www.mnot.net/cache_docs/#EXPIRES http://www.mnot.net/javascript/xmlhttprequest/cache.html The complete comp.lang.javascript FAQ is at http://jibbering.com/faq/ -- The sendings of these daily posts are proficiently hosted by http://www.pair.com.

The word "reduces" should be "reduce". -- Rob
