Expiring a web page

[sandman]

How do I make sure that the user goes "back" to an expired webpage? Is
there a way to trap the Back button and load a different page with the
"page has expired" message?

Expiring a web page

You could set the page headers such that the page expires
immediately. Look at Microsoft Knowledge Base Article -
234067 .
Basically , you would use the following :
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">
In ASP , it owuld be :
<% Response.CacheC ontrol = "no-cache" %>>
<% Response.AddHea der "Pragma", "no-cache" %>
<% Response.Expire s = -1 %>[color=blue]

Re: Expiring a web page

what you want to do is
Cache.SetCachea bility(HttpCach eability.Server AndNoCache);

followed by a Response.End();

This will trap the user on the page.

<<Cache.SetCach eability(HttpCa cheability.Serv erAndNoCache);
Response.End(); >>

Where do I do this? The bulk of the code is in the C# code-behind page.

Re: Expiring a web page

You can do this in the page, as a page directive, or in the code-behind.
Either one is supposed to work just as well as the other. Since you've got
most of the code in the code-behind page, it's probably best just to put the
caching calls there, too. You can specify in the Page_Load() method.

I just read an article on this: www.visualstudiomagazine.com ; the article
locator code is VS0311AN_D
