Global.asa
Should I define and open my ado connection in the Application_OnStart procedure and close in the Application_OnEnd procedure in Global.asa or is that a security risk?
If it's ok to define and open my ado connection in the Application_OnStart procedure how should I include a functions inc file in Global.asa?

Hi ncw,
I would declare the connectionstring in the Application_OnStart, however steer clear of instantiating objects in global.asa. As for including an inc file, not sure that this would work as the include files are specific to each page as far as i am aware.

I steer away from using connections and recordsets in ASP full stop. I do everything thru VB DLLs. Far easier to debug but not an option for everyone i guess!

Slimshaneey,
Just depends Slim, VB dlls do make it nice and easy but the main problem I have with using global.asa is the simple fact of having the connection open for the whole time the application is running. You still have to build in something to take account of the possibility that the server connection may fail in each page (you would of course do so in your dll as well). I also seem to remember (but cannot find the reference right now) that using objects instantiated from global.asa was a bad idea from the persistence point of view. Not so bad in application_onstart but with the issues surrounding Session_OnEnd not always being fired you could end up with memory leak and other issues from not being able to properly close and release the resources.

Ok I'm runing with bChan's comment, I've decided not to use the Global.asa and open and close the connection in each page.
Thanks

Hi Nick, how are things, got broadband in copythorne yet? I saw you had a campaign going a while back when I was hassling BT to get it sorted for me.

Tim,
Broadband in Copythorne ... ooh that's a sore point!! No, but I managed to trigger the exchange over Easter with some registrations. I had been working with an ex-Seattle Microsoft consultant from Lyndhurst on a scheme to unbundle the exchange but for various reasons after talking with a few providers it didn't happen. Since then we've looked at BT's Exchange Activate which is what Lyndhurst has got; now we are waiting for the BT RFS date which should be due next week.
Are you on Cadnam or Totton's exchange?

ncw,
I am on Totton exchange, unfortunately when I first ordered nearly 3 years ago they had TPON lines to the area I live in so couldn't put ADSL over it. Finally found an obscure document on adslguide.org that implied they were retrofitting with copper due end October last year. Spent a lot of effort hassling them and finally ushered in the new year with a brand spanking new connection. Mind you even BT's own systems and people didn't actually know that they had retrofitted with copper and it took a further couple of months before they updated the broadband checked on the website to admit that it was even possible.

Tim,
Sorry to hear about redundancy, still you're well qualified and I get the feeling the IT market is picking up this year although most jobs seem to be in London and Thames Valley.
I think there will be technical difficulties in the Cadnam area too, so it will be very interesting to see the RFS date!

You use includes in gloabl.asa like in any other files:
<!-- #include file="myfunctions.inc"-->
