Hi,
What can I do to block or erase the history of the Internet Explorer when a
user navigates in my ASP .NET 1.1 application?, I don't want that the user be
able to return to a previous page.

thnks.
 
Ok, but how can I turn off cacheing? Actually, I'm not using cacheing for
those pages.

What we have done (in 1 app): put some javascript in every page:
window.history.forward(1);

if there is nothing to forward to, this will not complain. However, if
the user used any form of "back button", he would immediatly be bounced
forward.

He means browser cacheing.

I use this in page load:

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

Also, I maintain session variables that hold the valid
navigate_to page, the current_page, and an allow_to_navigate
flag. When a page is loaded, I check if they are allowed
to navigate, and if so, if this is the page they are allowed
to naviage to. If not I redirect the user back to the "current"
page.

This scheme ensures that the user can not get to a page out
of sequence, or directly by typing a url, or pressing the back
button.
