问题
I have the problem that when I switch to other pages on the site, my background turns white and loads again. I know it has something to do with the IE cache and did some research about it. I already tried the most common fixes, both css and javascript, like the ones on this site: http://ieflicker.com/ but none of them works.
UPDATE (some code)
The site uses BODY with background-image: url('background1.jpg') as a part of its CSS. This seems to load image once and cache it in all the browsers but IE10. IE10 seems to reload it every time.
回答1:
Apparently IE10 doesn't cache image loaded via CSS despite all the hacks. You need to explicitly load it. E.g. if your body style mentions:
background-image: url('background1.jpg')
add this to your page's HTML:
<img src='background1.jpg' style='display:none' />
Now this will load and cache the image and the flicker will be avoided.
