use with the 404 trick

Once I've implemented a way to run a web server below another one
(actually Nanoweb below Apache, for more details see
http://nanoweb.si.kz/), because the Apache on one of my providers
servers was heavily misconfigured - so I handed work over to a
secondary WebServer+.

This trick also works without mod_rewrite support, and is therefore
also well suited for cheap WebSpace+. Put following into the
.htaccess of the dedicated wiki directory:

  #-- handle "not found" pages by ewiki
  ErrorDocument+ 404 /wiki/index.php
  DirectoryIndex+ 404 index.php

This will allow the "yoursite.php/ewiki.php" script to catch all
missed files, which would usually trigger a 404 error. Inside your
ewiki wrapper script, you must then however decode the originally
requested URL:

  $url = $_SERVER["REQUEST_URL"];               # Apache often uses this one
  $url = preg_replace("#^/wiki#", "", $url);    # strip wiki subdir name
  $_SERVER["PATH_INFO"] = $url;                 # make ewiki see it

The second step is very important, it strips the name of the
dedicated subdirectory from the URL, which cannot be done inside
ewiki.php.

   The $url from the above example could also be used as $id
   parameter to ewiki_page().           

It should be noted, that some Apache implementations are garbaging
POST requests in case of a triggered 404 error - but you can simply
test this by saving a changed WikiPage+.

See also the "fragments/404finder.php" example on this.

Do not forget to enable EWIKI_USE_PATH_INFO+, as it is per default
disabled for Apache servers!

You cannot modify the README file, but anyhow any ideas or suggestion should as usually get filed on BugReports, UserSuggestions or even better the README.Discussion.
