Something odd just happened when I logged on! (page 6)

So far, I'm always Vidiot.

I can't tell you all what a relief it is.

I've left it a while to post - just refreshing/clicking on 'active topics' - lots of names. Not logged in or out. It must be something to do with who is browsing active topics at the same time.

I'm tornapart now.

So, I was just checking a few things on the site and found the "OutputCache" settings were disabled.

"Hmmn, that's strange", I thought, "What the hell was I thinking leaving that disabled? I will enable it immediately ..."

For those who don't know what output caching is, it means that the rendered version of a page is cached and can be served for other matching requests instead of having to hit the database and re-build the entire page each time. It really does make things faster and would be perfect ... if people's signed-in username didn't appear at the top of the page !

So yes, whoever happened to view the page when the cache expired and the page was re-generated (every 30 seconds) would then appear for everyone else requesting the same page for the next 30 seconds.

There are no security implications - the permissions are checked separately to the caching and the only pages that were being cached were the public ones (active topics, subject views etc...) so the issue is really just cosmetic (it shows the wrong username).

Sorry for the confusion, my dumb mistake ... "normal service will be resumed shortly" as Basil Fawlty would say :)
