RE: FN-FORUM ASP Question - Simple I hope.

OK Matthew,
You've tempted me... I've looked at the references I've looked at Dave's and
Jon's code and I am finding this a very useful tutorial... NOW let's see how
the expert would code the problem then!

I take it the reason why you're constructing a Dictionary from the
querystring values is for debugging? You know that in production, you'd use
Request.QueryString to get the values back, right?

I'm still not happy with the scalability of this solution. Opening and
parsing the XML file per request would be wrong! This kind of thing with
classic ASP is a nightmare. I seem to remember as well that loading
Dictionary objects into the Application variables (under no circumstances do
this in Session!) causes horrible threading problems in ASP and would
further complicate the problem.

I think this is a great demonstration of how to solve the problem, but in my
opinion it's unworkable in anything other than a very small, very very low
traffic site.

Not wishing to seem overly cocky, but I do have some qualification in this
area:

...I just don't want you running into a major scalability problem! =)

Cheers,
Matthew

OK, I've created a small asp page and XML file which I've attached to this
post. I hope we're allowed to attach files :P

Note: On line 44 we assign a dictionary value and key, this key and value
will be URL encoded. So you will need to write a routine to covert those
back to plain text. Sorry for leaving this out, but I'm snowed under with
some big projects.

I've also left alot of the error checking routines out. I wanted to leave
you some work. :P
