   Abstract:
     SSL service for W3SVC.
     New SSL service is introduced to IIS6. 
     In the dedicated (new process mode) it will run 
     in lsass. That should boost ssl performance by eliminating
     context switches and interprocess communication during
     SSL handshakes.
     
     In the backward compatibility mode it will not do much.
     Service will register with http for ssl processing, but w3svc
     will register it's strmfilt and http.sys always uses the
     last registered filter so that the one loaded by inetinfo.exe 
     will be used.
