Weird caching behavior?

Andrea L. Williams

My development system and the production system run the same basic pages, as
you would guess. After I browse the production site and then switch to my
development site, using IE 6.0, for some reason the javascript for my menu
still thinks I'm on the production site and any menu items that I press go
to the production site instead of development.

In case you are thinking that it's a browser caching issue, I just tested
with Netscape and get the same results.

There is one thing that seems to correct the problem, and that is to put my
system into debug mode and back out again. But as soon as I go back to the
production server, then back to my dev server in the browser, same problem.
All menu links go back to production from the dev home page. Then I have to
put it back into debug and out again, then the link go back to the correct
server.

Has anyone else had this problem? I hope I'm explaining this well enough...

A little more info here:

All pages have two the 'no-cache' and 'expires' meta tags.

The site name for the javascript is supposed to get set in the BaseCommon
class of the site which come from the Web.Config file.

My dev system is Win2K and has been updated by MS Update. I can't remember
having this problem when I was on the Win2003 Server. (I had other problems
though and went back to Win2K).

META tags are all but useless to prevent caching. You must use proper
HTTP constructs such as Cache-Control headers. You can control them
using the System.Web.Http CachePolicy class.

Static content is cheap anyway, the file system...

Weird Session Behavior in Browser

I'm pretty sure this is an unusual case and I suspect it has as much to do with what the browser is doing as it does PHP on the server, but the behavior defies anything I would have expected.

The easy way to turn off automatic updates for Windows 10/11

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. 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,...
