The wiki mentions that you could include a JS rewrite command in the per-directory webctrl.ini file:

REWRITE

Specifies a Javascript snippet which can modify the http_request.request_string. This allows internal redirects like the RewriteRule feature in Apache .htaccess files. The key must *begin* with the string “Rewrite” which may be followed by any legal INI key characters. The order of execution is not guaranteed.

Does anyone have an example of this?

Here's an example:

JSPreExec=load(js.startup_dir+'/doku_rewrite.js');
Rewrite=doku_rewrite();

And here's the contents of doku_rewrite.js:

function doku_rewrite()
{
var n=http_request.request_string;

// Simple replacements...
n=n.replace(/^([^\?]*\/)_media\/(.*)/,"$1lib/exe/fetch.php?media=$2");

n=n.replace(/^([^\?]*\/)_detail\/(.*)/,"$1lib/exe/detail.php?media=$2");

n=n.replace(/^([^\?]*\/)_export\/([^\/]+)\/(.*)/,"$1doku.php?do=export_$2&id=$3 ");

// This handles adding doku.php to the index bit of the URI
var pi = http_request.path_info;
if (pi[0]=='/') {
pi=pi.substr(1).replace(/[\-\[\]\/\{\}\(\)\*\+\?\.\\\^\$\|]/g, "\\$&");;
n=n.replace(new RegExp('^(.*)('+pi+'(?:\\?.*)?)$'), "$1doku.php?id=$2");
}

// If the URI ends with a slash, stuff in doku.php at the end.
n=n.replace(/^([^\?]*\/)(\?.*)?$/,"$1doku.php$2");

// index.php becomes doku.php
n=n.replace(/^([^\?]*\/)index.php/,"$1doku.php");

// Handle it.
if (n != http_request.request_string) {
// Replace all but the first '?' with '&'
n=n.replace(/(^.*\?[^\?]*)\?/g,'$1&');
http_request.request_string = n;
return true;
}
return false;
}

A line like this in the root of a webctrl.ini file would generate a log message whenever that directory or any file in it was requested:

RewriteOne=log('Generated by RewriteOne');

You could limit it to a specific file or pattern by putting it in an ini section, per the normal webctrl.ini rules. And I guess you could have more rules named RewriteTwo, RewritePizza, whatver you like.

I have tested this but I haven't done anything useful with it. I'm not sure if it's limited to modifying http_request.request_string, or if it's capable of more and that's just the intended use.
