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

Who said anything about using the XML approach per request?. I only gave
some ammunition for Jonathan to develop a solution. There are other ways
around this.

On other thing, how we use Request.QueryString when the keys/values we need
aren't in the querystring of the current HTTP request?. If you read
Jonathan's first post then you can see this.
