setting no cache

[davebat]

Hi I have a form, 3 pages in i submit data. On this page I have set no cache

<% 
    Response.ExpiresAbsolute = DateTime.Now
    Response.Expires = 0
    Response.CacheControl = "no-cache"
    Response.Buffer = True
    Response.Cache.SetCacheability(HttpCacheability.NoCache)
    Response.Cache.SetExpires(DateTime.UtcNow)
    Response.Cache.SetNoStore()
    Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches)
%>


<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">

after successfully submitting I create a session to say user has submitted and redirect to a summary.

Then in page load of submission I check to see this session exists and if so I forward to summary.

Now I submit, go to summary and press back. Submission loads from server and sees session exists and sends to summary. It works fine.

However when I press back again it ignores the submission and goes to the page before.

Can anyone help me with this or at least explain whats happening.

Thanks in advance.

Hello,

Just to confirm, at you testing this out of Visual Studio using the built in web server, or out of IIS?
