//  useragent.php
//
//  In the Mobile Test Harness [1] user agents where identified by full
//  user-agent strings. For the CSS2.1 test harness there is a desire to
//  allow consolodated results for user-agent strings representing the
//  same browser type, version number and/or platform (OS).
//
//  Herein functionallity is provided whereby a user-agent string can be
//  posted for comparison to a database of known user-agent strings.
//  If the user-agent string is known, then a unique id number that
//  identifies the user-agent within the context of the test harness is
//  retrieved and used in redirecting the user back to testsuite.php.
//  If the user-agent is not in the database, then the provided string
//  is parsed to obtain a reasonable guess for the browser, version, and 
//  platform information. This parsed information is stored in the database
//  and a newly generated id number ascotiated with the new user agent
//  is retrieved and used.

  //  If no test suite is identified then any provided, then no additional

  //  The parameters posted to a page generated by an object of this class
  //  should also identify an alternate user agent for which data is to be
  //  entered.

  //  If no alternate user agent is identified then the user is directed

  //  Otherwise the provided user-agent string is processed as described

  //
  //  All other posted parameters are ignored and consequently dropped
