Caching

How do I stop users caching my site

[chris_f]

I have a site that uses a session variable to decide which design template to send the users. The problem is that the pages get cached. With the caching, if the variable changes they need to refresh to see the new design. How do I stop the browsers from caching my pages?

Are you using a serverside language?

If you're using ASP, you can include this line at the top:

<% Response.Expires = -1 %>

There are also meta tags for pragma no-cache, but they don't work as well.

If you want it to work across the board in asp use this

<%
Response.Expires = -1
Response.Expiresabsolute = Now() - 2
Response.AddHeader "pragma","no-cache"
Response.AddHeader "cache-control","private"
Response.CacheControl = "no-cache"
%>

Dont know exactly what it all means, but seems pretty reliable :)

Maybe someone could explain..

Response.Expires = 0
Response.Expiresabsolute = Now() - 1
Response.AddHeader "pragma","no-cache"
Response.AddHeader "cache-control","private"
Response.CacheControl = "no-cache"
