 * 27/02/2002 - active session query caching added
 *            - PHP support utils

phpWebLogAnalyzer TODO list
---------------------------

- change query string column from text to [var]char(255) and make index;
  raw accesses table than should have not varchars but pure chars
- getSessionsCount() and getActiveSessions() result caching
- replace every SQL substring() with PHP substr(); it could increases (not only)
  network performance
* property manipulation methods (get/set value, get array)
- possible bug: SQL clausule substring() called on non-string types
- possible bug: calling getSessionCount() without registerAccess()
  - solution: check if was $_props array already processes and if not, than
    process that array before doing getSessionCount() job
- create utility for converting data from weblog_core_accesses table to 
  weblog_accesses table
  - a good idea could by to convert only closed sessions to avoid some type
    of desynchronization with having two IDs for one session
* add support for weblog_core_accesses table; creating entry for weblog_accesses
  is very difficult for CPU and SQL server
  - table is called weblog_accesses_raw
- source formating PEAR compliancy
* class style PEAR compliancy
- PEAR compliant error handling
- ident stuff: move index column and table name from *_username to *_user
- think about possible table joins:
    weblog_ident_usernames w/ weblog_remote_idents
    weblog_http_hosts w/ weblog_remote_hosts (what if HTTP_HOST is IP address?)
* session_id column
- Perl API functions for register hits
- web interface (frontend) for analyzing and manipulating with statistics

- why this doesn't work?
