Problem Statement :   association of a file extension ...with a handler

Analysis :  in the context of  windows as a os ....ability to compress a compressed file with compression handler
              and amount of  success achieved ??

             ...ability to attach or associate  two different content handler's for same file extension ?? ,

             audit -trail ...logging ....change of content handler with a associated file extension ...for instance above scenario.

            enhance-ment of registry with a configurable option...the ability to track or trace modifications under the same
            tree or branch or hierarcy ...ability to compare the old and the new set of configuration settings 

            viz. keys, values, data  i.e. trace additions, deletions, modifications as envisaged above.


         Given the context  ...did the concept of content handling and handler origin from CGI , and the implementations
         or versions of the same under OPERATING SYSTEMS ...WINDOWS ??

              

 Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in 
      
       http://uk.geocities.com/ravivenkatus/projects.pdf
       http://ravishankarkv.tripod.com/projects.pdf
        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
