Window to DPO's thoughts: A forensic analysis of the IE6 BackgroundImageCache command identifier

IE would "normally" check with your web server for newer versions of the css background images prior to applyng a css rule, no matter what is the value of the cache option. Make it "Every visit to the page.", "Automatically" or "Never", it does not matter, IE wants to know anyway.

Whats seems to be the problem

Internet Explorer 6 seems to check for a newer version of the background-image css property on links (A tag) every time you move the mouse over a link.

/*@cc_on @*/  
/*@if (@_win32) 
try {
  document.execCommand('BackgroundImageCache', false, true);
} catch(e) {}
/*@end @*/
