Using the browser back arrow

[Denise]

In my application, I am setting cookies used for other pages based on the
current row selected. But when the user presses the 'back' button, the
pageload event does not get called and the record they are viewing does not
match the cookie and can lead to data entry errors. Is there a way to
resolve this?

Thanks,
Denise

When browser back button clicked, the page is loaded from users cache.. one
way is to expire the first page , so that when the user clicks back button
from second page, the browser shows a message that page is not available,
forcing them to use the navigation provided in the site ..

private void Page_Load(object sender, System.EventArgs e)
{
ExpirePageCache();
//.......rest of the page_load logic....................
}
/// <summary>
/// This function prevent the page being retrieved from broswer cache
/// </summary>
private void ExpirePageCache()
{
Response.Cache.SetCacheability(HttpCacheability.No Cache);
Response.Cache.SetExpires(DateTime.Now-new TimeSpan(1,0,0));
Response.Cache.SetLastModified(DateTime.Now);
Response.Cache.SetAllowResponseInBrowserHistory(fa lse);
}
