Does anyone have experience with passing variables from an

I'm not even aware of a way to pass variables from one ASP page to another
ASP page.
You can certainly pass information in Forms, QueryStrings and Cookies from
browsers to ASP scripts, and can pass a Response from a script to a browser.
In neither case is a variable passed from one script to another. Even
Server.Execute() does not allow the passing of variables (though Request and
Session objects are shared).
There is always the possibility of using a proxy for the browser to allow
two scripts to interact. For example, one script can use the ServerXMLHTTP
object to send a Request and receive a Response from another script. That
interaction is still limited to the same restrictions as a browser-server
one, however.
What about session variables? There is still no script-to-script
interaction. IIS generates a unique session ID and passes it to the browser
as a transient cookie. Every time a Request arrives with an ASP session
cookie, IIS looks to see if there is a matching active session, and if so,
exposes the corresponding session variables to the script.
As Bob suggested, you can use a DB as a temporary store that is available to
both web servers, but unavailable to the public. It is a good idea to
generate unique IDs to identify these "sessions", and if you are using SQL
Server, you can just generate a GUID with NEWID(). Send the GUID back to the
browser in a cookie, then redirect him to the other server.
This is, of course, a simplification. But you get the idea.
