From: FAQ server on 11 Aug 2010 19:00 ----------------------------------------------------------------------- FAQ Topic - Why are my rollovers so slow? ----------------------------------------------------------------------- Images are cached by the browser depending on the headers sent by the server. If the server does not send sufficient information for the browser to decide the image is cacheable, the browser will check if the image has been updated every time you change the src of an image (in some user settings). To overcome this you must send suitable headers. <URL: http://www.mnot.net/cache_docs/> 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. |
