cookie deleter javascript
a few of the users of my website are having trouble seeing new content after it's updated. i'm guessing this is a problem with cookies? can javascript check if there is already a cookie for my page, and if it is not identical delete it? or do i have no clue what i'm talking about. i don't have any other scripts concerning cookies on my pages. thanks.

No it isn't a problem with cookies, it's a problem with caching. Caching is when a persons computer downloads a webpage and stores the files so that the next time the person returns the pages don't have to download again.

The people can either use the Refresh button on the browser or you can insert this code in the header of the page to prevent caching:

PHP Code:
<META HTTP-EQUIV="Expires" CONTENT="Fri, Jun 12 1981 08:20:00 GMT">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache"> 
Hope this helps,
BlazeQ

Can the same thing be done in ASP using response.expires? If so, what's the difference?

You can do the same thing by doing a:
PHP Code:
<% Response.CacheControl = "no-cache"
Response.AddHeader "Pragma", "no-cache" %> 
Response.ExpiresAbsolute = #Jan 01,1990 12:00:00# 
Response.Expires = -1 %> 
As for the difference, with Response.Expires can be set on specific things. I've seen a lot of people us it to set a link to expire. So after so many minuites or so the link will not be cached and will need to be reretrieved.
Some say that there are problems with the Response.Expire so they us the META tags. I've never really found that to be true, but I never really tested it a whole lot.
