<!-- | Description:														 | -->
<!-- |      This file is responsible for handling the logon efforts of   | -->
<!-- |      solution.  When the user presses the logon button, the       | -->
<!-- |      action is handled in this file.  Five variables are created, | -->
<!-- |      some are initialized with data from the posting page.  When  | -->
<!-- |      the variables are set, a call is made to the Logon method of | -->
<!-- |      viEngine object, which returns a long.  If the return value  | -->
<!-- |      is zero, then the logon was successful, and the user is sent | -->
<!-- |      to the next page in the solution.  Otherwise, the user is    | -->
<!-- |      redirected to the default.asp page (logon page).             | -->

<!-- |	1. This file is named "prLogon.asp", this naming convention was  | -->
<!-- |       was chosen so that 'pr' represents process followed by the  | -->
<!-- |       name of the form it works for.  In this case, this is the   | -->
<!-- |       process page for the Logon page (default.asp).				 | -->
