//

//
// NONE: This is roughly the old (pre 1.3.4) behavior.  PhpWiki will
//       instruct proxies and browsers never to cache PhpWiki output.
//
// STRICT: Cached pages will be invalidated whenever the database global
//       timestamp changes.  This should behave just like NONE (modulo
//       bugs in PhpWiki and your proxies and browsers), except that
//       things will be slightly more efficient.
//
// LOOSE: Cached pages will be invalidated whenever they are edited,
//       or, if the pages include plugins, when the plugin output could
//       concievably have changed.
//
//       Behavior should be much like STRICT, except that sometimes
//       wikilinks will show up as undefined (with the question mark)
//       when in fact they refer to (recently) created pages.
//       (Hitting your browsers reload or perhaps shift-reload button
//       should fix the problem.)
//
// ALLOW_STALE: Proxies and browsers will be allowed to used stale pages.
//       (The timeout for stale pages is controlled by CACHE_CONTROL_MAX_AGE.)
//
//       This setting will result in quirky behavior.  When you edit a
//       page your changes may not show up until you shift-reload the
//       page, etc...
//
//       This setting is generally not advisable, however it may be useful
//       in certain cases (e.g. if your wiki gets lots of page views,
//       and few edits by knowledgable people who won't freak over the quirks.)

// The next section controls how many old revisions of each page are
// kept in the database.
//
// There are two basic classes of revisions: major and minor. Which
// class a revision belongs in is determined by whether the author
// checked the "this is a minor revision" checkbox when they saved the
// page.
// 
// There is, additionally, a third class of revisions: author
// revisions. The most recent non-mergable revision from each distinct
// author is and author revision.
//
// The expiry parameters for each of those three classes of revisions
// can be adjusted seperately. For each class there are five
// parameters (usually, only two or three of the five are actually
// set) which control how long those revisions are kept in the
// database.
//
//   max_keep: If set, this specifies an absolute maximum for the
//             number of archived revisions of that class. This is
//             meant to be used as a safety cap when a non-zero
//             min_age is specified. It should be set relatively high,
//             and it's purpose is to prevent malicious or accidental
//             database overflow due to someone causing an
//             unreasonable number of edits in a short period of time.
//
//   min_age:  Revisions younger than this (based upon the supplanted
//             date) will be kept unless max_keep is exceeded. The age
//             should be specified in days. It should be a

//
//   min_keep: At least this many revisions will be kept.
//
//   keep:     No more than this many revisions will be kept.
//
//   max_age:  No revision older than this age will be kept.
//
// Supplanted date: Revisions are timestamped at the instant that they
// cease being the current revision. Revision age is computed using
// this timestamp, not the edit time of the page.
//
// Merging: When a minor revision is deleted, if the preceding
// revision is by the same author, the minor revision is merged with
// the preceding revision before it is deleted. Essentially: this
// replaces the content (and supplanted timestamp) of the previous
// revision with the content after the merged minor edit, the rest of
// the page metadata for the preceding version (summary, mtime, ...)
// is not changed.

 * Any of these parameters which are left undefined will be deduced
 * automatically. You need only set them explicitly if the
 * auto-detected values prove to be incorrect.
 *
 * In most cases the auto-detected values should work fine, so
 * hopefully you don't need to mess with this section.
 *
 * In case of local overrides of short placeholders, which themselves 
 * include index.php, we check for most constants. See '/wiki'.
 * We can override DATA_PATH and PHPWIKI_DIR to support multiple phpwiki 
 * versions (for development), but most likely other values like 
 * THEME, $LANG and $DbParams for a WikiFarm.

 * http://www.example.com/index.php?pagename=HomePage
 * then define 'USE_PATH_INFO' as false by uncommenting the line below.
 * NB:  If you are using Apache >= 2.0.30, then you may need to to use

 * on prettifying your urls.

 *
 * If you do this, you should set VIRTUAL_PATH here.
 *
 * E.g. your phpwiki might be installed at at /scripts/phpwiki/index.php,
 * but  * you've made it accessible through eg. /wiki/HomePage.
 *
 * One way to do this is to create a directory named 'wiki' in your
 * server root. The directory contains only one file: an .htaccess
 * file which reads something like:
 *
 *    Action x-phpwiki-page /scripts/phpwiki/index.php
 *    SetHandler x-phpwiki-page
 *    DirectoryIndex /scripts/phpwiki/index.php

 * view the page you just saved.)
 *
 * Some web service providers (notably free European Lycos) don't seem to
 * allow these redirects.  (On Lycos the result in an "Internal Server Error"
