加载一次刷新页面

Question

this should be so simple but I can't get it to work, all I want to do is to refresh my page immediately once when it is loaded. I don't want to stop caching as much of the data on my site stays the same. I don't want to go to a different url ie www.mysite.com/page1.php?refreshedpage because my url's are clean and easy to follow.

I have images using the same file name which get changed, hence when a user accesses my site, they see the old cached images.

Cheers

Add to your images something like the following:

<img src="/images/image.jpg?refresh=20110524" />

I just used the date, but you can use whatever you want. This will trigger the browser to think it is a new image, and will download it, instead of using the cache, for all users.

No matter what querystring you use, after the image file name, it will still load the same image, although the browser will think it's a different image.
