Many of my pages, including the grids in them, are not refreshing when they come back to the page. I was wondering how to get the pages to refresh just one time onload? The only way i could get this to work was by doing a javascript refresh statement, but of course it throws itself in a loop.
How can i just refresh once when the page is loaded?
Thanks!

Not sure what language you are using but I typically have a bunch of meta tags in my pages to eliminate caching. There is some Coldfusion tags but if you are in another language you can ignore them.
<!--- these tags will expire a page so that when they hit the back button you won't get problems looking at old data. it was also recommended to add in the title tag a time. <title>Survey
<cfoutput>#TimeFormat(NOW(),"mmsstt")#</cfoutput>
</title>
This trick came from CF tips --->
<meta http-equiv="Expires" content="Wed, 01 January 1997 00:00:00 GMT">
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="expires" content="-1">
<cfheader name="cache-control" value="no-cache, no-store, must-revalidate">
<cfheader name="pragma" value="no-cache">
<meta http-equiv="expires" content="0">

Thanks for replying, but I found a much easier work around for this. In my IIS settings for my website, I put an http header to tell each page it expired in the past, any date before the current will work. That way each page load see's that the page has expired and refreshes automatically.
Thanks for all your suggestions and ideas though!

 I want to know how to refresh once because I am creating an image viewer in asp and when I use redirect it doesn't refresh the page. Can anybody here help me? Thanks... I tried the code upside, but none worked.

1. Use redirect with some random parameter, so that the Web browser will not cache the previous URL. For example URL?rnd=123.
or 2. Use some HTML meta tags that will tell Web browsers not to cache that page.
or 3. Expire the cache otherwise. There should be several methods for this which you can find on the net:
