  26 For communication with Lotus Domino groupware server.
  27
  28 Server requirements: Domino 5.0.2 and above with Web Access.
  29
  30 1) Tries to read user's notes.ini for mail database name.
  31 Windows registry keys for notes.ini location:
  32 HKEY_CURRENT_USER\Software\Lotus\Notes\6.0\NotesIniPath
  33
  34 2) Authenticates to server (HTTPS POST, plaintext login/password over SSL)
  35 https://[domino_server]/[databasename].nsf/?Login
  36 Content-Type=application/x-www-form-urlencoded
  37 Username=[email]&Password=[password] (params are url-encoded)
  38 Saves auth cookie.
  39 Set-Cookie=DomAuthSessId=17D0428F7B9D57D4D0B064AE42FD21F9; path=/
  40
  41 3) Queries Calendar data (HTTPS GET, result is XML)
  42 https://[domino_server]/[databasename].nsf/[viewname]?ReadViewEntries
  43 https://[domino_server]/[databasename].nsf/($Calendar)?ReadViewEntries&KeyType=time&StartKey=20090805T000000Z&UntilKey=20090806T000000Z&Count=-1&TZType=UTC
  44 Uses auth cookie.
  45 Cookie=DomAuthSessId=17D0428F7B9D57D4D0B064AE42FD21F9
  46
  47 It is able to retrieve our Calendar information (Meetings schedule,
  48 subject and location) from Lotus Domino for subsequent publishing.
  49
  50 Ref. for more implementation details:
  51 https://sourceforge.net/tracker/?func=detail&aid=2945346&group_id=194563&atid=949934
  52
  53 Similar functionality for iCalendar/CalDAV/Google would be great to implement too.
