[TYPO3-core] RFC: #10724: Feature: Provide a check that compare a given URL with the host, TYPO3 is running on!

[Marcus Krause]

Hi,

This is SVN patch request.

Type: Feature

Bugtracker references:
http://bugs.typo3.org/view.php?id=10724

Branches: trunk


Problem:
I'd like to allow BE editors to reference resources (URL) but only if
they are on the same host TYPO3 is running on.

Unfortunately there's no nice API to make such a check.


Solution:
Provide such a nice method.


Note:
The attached patch provides following additional functions:

t3lib_div::isURL($url)
 checks if a given string is a URL

t3lib_befunc::isAllowedSite($url)
 checks if a given URL matches the host TYPO3 is running on

In addition, Unit Test are added to check above functions work properly.


Marcus.
