Problem with caching asp.net web pages

Question

I want my asp.net/C# 2008 web pages not to be cached on the client side or on the server side.

How can i do this?

Answer 1

For the client side, you want to use No-Cache

Here is a link describing how to configure the response object without caching on the server side:

http://www.extremeexperts.com/Net/FAQ/DisablingBackButton.aspx

Response.Buffer = True Response.ExpiresAbsolute = Now().Subtract(New TimeSpan(1, 0, 0, 0)) Response.Expires = 0 Response.CacheControl = "no-cache" 

Answer 2

The page is cached, so the decision not to cache it on the client side is to put this tag:

 <%@ Outputcache Location="None"%> 

before the page tag:

 <%@ page > 

The result is as follows:

 <%@ OutputCache Location="None" %> <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> 

Answer 3

In your question, you do not specify the cache on both the client and the server. For me, this means no caching anywhere.

This will prevent any caching anywhere.

 Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1)); Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.Cache.SetNoStore(); 

Either put this on the loading of pages that you do not want to cache, or create a base page class.
