ASP Debugging

Ensure all objects are being closed and set to nothing after they have been finished with.

Also if you are using Access database these can be reource intensive if they are of a reasonable size.

Sessions will auto expire.  Be wary using them though, try not if if necessary.  You can almost always use cookies as an alternative.

When I say all objects I mean all objects!  Anywhere where there is a Set obj = New something, that needs to be wiped before the page finishes executing.

Problem with cookies is they use up server resources.  Stored in memory on the server.  Also you don't have as much control over it's expiry.  However, there are a couple of things sessions can do but not cookies.  So far in the things I've made I have found little use for them.

Not sure about viewing all open objects the quick and dirty way.  It's better to build up good coding standards and practises so you know the page is clean.  You will probably manually need to go through the whole thing.
