A number of readers have asked if it is possible to "call" another ASP page in the way you might call a subroutine in another language. Currently, the only options you have available are to use Response.Redirect to transfer control to the page, or to include the code you want to call as part of the same ASP page and put it in a subroutine or function.
However, IIS 5.0 (ships with Windows 2000) has several new methods that allow you to execute another ASP page and return control to the original page when the code is complete. The Execute method of the Server object will run the code in another ASP page. Besides breaking up your code, this method can also be used to do conditional includes of other files, which the standard server-side include directives can't. The Server object also has a new Transfer method, which passes the contents of all server-level objects, such as the Response object, to the next page. This method will make it much easier to have pages working together and will save you some time in having to code all the data values into the URL, a Session variable, or some other mechanism.
