Turn off browser cache

[A.M]

Hi,

How can I disable the end-user's browser cache inside the Page_Load event?

Thanks,
Alan

This code should do the trick:

Response.Expires = 0
Response.Cache.SetNoStore()
Response.AppendHeader("Pragma", "no-cache")

Thanks for help,

Can I use them inside Application_BeginRequest in Global.aspx?

Hi Alan,

It will be Ok to put Steve's code in Application_BeginRequest.

This code should do the trick:

Response.Expires = 0
Response.Cache.SetNoStore()
Response.AppendHeader("Pragma", "no-cache")

That is a myth.

OK, that's probably a harsh way to put it.

What it does is scare off HTTP 1.1 proxies and "upward-compatible" HTTP 1.0
proxies like squid. The browser itself can choose to ignore any of those
headers. Try Opera ;-)

Cheers,
