After logging out of my test site I would like to be able to not allow the
user to navigate back to previous pages. It's not super-important because if
they try to do anything the login state has been wiped and anything that
posts back or refreshes the page will send them back to the login screen...
but it would be nice if either the navigation history is wiped, or some
setting is set that causes all the previous content to be expired. Is that
possible?

use this code to prvent the page from being cached..
private void Page_Load(objec t sender, System.EventArg s 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 (HttpCacheabili ty.NoCache);
Response.Cache. SetExpires(Date Time.Now-new TimeSpan(1,0,0) );
Response.Cache. SetLastModified (DateTime.Now);
Response.Cache. SetAllowRespons eInBrowserHisto ry(false);
}

This would seem to always prevent the user from navigating back, and not
just after some action. That would annoy most users. Is there a way to
expire all previous pages' caches retroactively?

I believe, it is not possible to remove any page other than current
page from cache.

In general no. If the browser navigates back through it's local
history, there's nothing you can do.

With the body tag calling out 'window onload', a function with a
'window.open' fails at the 'window.open' line. If I cut out the body
tag, the function executes as normal.
At first I thought it was the entire function failing, but I tested
with alerts and found that it was only the 'window.open' that fails to
execute.
The function is being called by a link, and I suspected some problem
with the body alink/vlink but after cutting that out...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
