How to disable cache

I know this question has been asked a dozen times but in all the posts I can't find an answer that works for me.

I am trying to completly disable all cache from a page, so when the user goes back using the browser buttons, there appears the typical sign of "This page has expired".

So far I've tried the page directive:

<%@ OutputCache Duration="1" Location="None" %>

The Meta tags:

And the code:

Response.ExpiresAbsolute = DateTime.Now

Response.Expires = -1441

Response.CacheControl = "no-cache"

Response.AddHeader("Pragma", "no-cache")

Response.AddHeader("Pragma", "no-store")

Response.AddHeader("cache-control", "no-cache")

Response.Cache.SetCacheability(HttpCacheability.NoCache)

Response.Cache.SetNoServerCaching()

But every time the back button is clicked, there appears the previost page.

How can I solve that?

Thanks

Re: How to disable cache

By OutputCache directive you asking to hold the page in cache for 1 second. You need to remove that if you dont want to cache it.

Add these lines in the html meta section

and in the page_load write this

Response.Cache.SetCacheability(HttpCacheability.NoCache);

Thanks

Re: How to disable cache

I have already tried removing the OutputCache directive, with the same results. I was expecting that by caching the page for 1 second, after that second it would discard it. I've tried usind another value, but OutputCache doesn't accept non-positive numbers.

As I wrote in my previous post I have already used the meta tags and I didn't mention it, but the "response" code is in the page_load too.

I also didn't say that I'm using asp.net 2.0

Thanks

Re: How to disable cache

Setting the OutputCache for 1 second displays the content from cache for one second and after that any new request will get data from server. I tried the code you have given and its displaying the typical page expired message.

Thanks

Re: How to disable cache

I've created a small hellowWorld type project, implementing the cache disabling method discussed.

There are just 2 pages and one of them contains a linkButton to the other. I've built the project and uploaded it to a web server but I still don't have the desired result. I've tried it using explorer 6.0 and mozilla firefox 2.0.

If anyone would be so kind, could you have a look at it. You can find it zipped inside the following address.

Re: How to disable cache

Actually, it's impossible to disable cache at least for ff and chrome (feature of these browsers).
