[not a bug but weird] too many 'valid' URLs for the same page

say we have an alias for ’documentation’ with ’.php’ as suffix. Without turning on parent alias, that would be

http://www.mysite.com/documentation.php

But there will be millions of duplicated URLs that load up the same page, i.e.

http://www.mysite.com/abc/documentation.php
http://www.mysite.com/def/documentation.php
http://www.mysite.com/kmlllasd/documentation.php
http://www.mysite.com/342344/documentation.php

Instead of returning 404. You get what I mean?

Just wrote a simple plugin to fix that.

Why writing this simple plugin, I have some confusions:-

1. Should I use $modx-> or $this-> in a plugin?

2. Should I use $this->sendErrorPage(); or

$this->documentMethod = ’id’;
$this->documentIdentifier = $this->config[’error_page’];

Use $modx->

$this-> is only used inside the MODx parser class itself. Outside, you are using an object named $modx which gets instantiated by index.php. If you are loading the parser into an external script, you need to instantiate the object yourself.

This issue has been also discussed here and there is some fix attached to that thread. But it seems that the issue is not still fully resolved. If there’s not a bug report for this yet, would you mind creating one?

The bug is already filed here
