Pages not expiring

marthaj · October 30th, 2003, 10:54 PM

Hi folks

below is the code that issue on each of my pages prior to the <HTML> My pages should expire, but they don't.
Can anyone tell me why they aren't expiring??
Sure would appreciate it :-)

<%@ Language=VBScript %>
<%Response.Buffer = true%>
<%Response.Expires = 0%>
<%Response.CacheControl = "no-cache"%>

Hi there,

You may want to try this:

Code:

<%
  Response.ExpiresAbsolute = #1/1/1980#
  Response.AddHeader "cache-control", "private"
  Response.AddHeader "pragma", "no-cache"
%>

This will prevent the page from being cached.

Regards,

Imar

Did you empty your cache prior to testing it?

Anyway, I'm using the following:

Code:

Response.CacheControl = "no-cache"
Response.AddHeader "Pragma", "no-cache"
Response.Expires = -1

what does the "Pragma" mean ??

I am another question about pages expiring.
Do I understand the page will expire afer the user has been redirected to another page?
Just when does a page expire?
Thanks so much, I do appreciate it:D

The pragma instruction is used to prevent any servers between you and the remote server (like proxies and caching servers) from caching the page.

A page will expire when its expire date has passed. With the code below, a page will expire immediately. This means that when you navigate to another page and then press the Back button of your browser, you should get a new page.

Thank you. Some pages are expiring and some are not.
I have no clue why some do and some don't.
I have looked at the coding and see no real reason for it.
Would anything have to do with Internet Explorer settings??
I am working in localhost mode.
And on the web server, some do expire and some don't.
It's really driving me nuts!

I can imagine it's driving you nuts. How did you configure Internet Explorer? (Not that it should matter, I think.). I think the following code is the definite way to prevent caching (note the change in the cache-control).

Code:

Response.ExpiresAbsolute = #1/1/1980#
Response.AddHeader "pragma", "no-cache"
Response.AddHeader "cache-control", "private, no-cache, must-revalidate"

If this doesn't help, check your browser. Did you clear the entire cache (with the browser closed) before you requested your pages?

Imar
thank you, interesting url.
I cleared my cache and temp internet files and my history and still no go.
I am going to add the snippett of coding you just psoted and see what happens. I ahve one page that does expire and I see no difference as to to coding why the others won't expire. I will keep you posted.
this has got me going in circles

Do you kno whow I can disable the backspace key? I know I can if I use window navigate etc. But I am using server-side coding.
I would think I would still be able to disable it on the window or document onload event.
