[TYPO3-english] EXT: felogin - What's the difference between the GET/POS and the REFERER options?

[Peter Klein]

In the SVN version of the felogin extension, the manual have been updated.
http://forge.typo3.org/repositories/revision/27/7317

The GET/POST option is described like this:
Redirect the visitor based on the GET/POST variable 'redirect_url'. If the 
TypoScript configuration config.typolinkLinkAccessRestrictedPages is set, 
the GET/POST parameter 'return_url' is used.
Example url:
http://www.domain.ext/index.php?id=12&redirect_url=http%3A%2F%2Fwww%2Edomain%2Eext%2Fdestiny%2F


And REFERER is is described like this (which is wrong):
The referer page is used for the redirect. This basically means that the 
user is sent back to the page he originally came from.

The REFERER option works exactly like the GET/POST method, only difference 
is that you need to set "referer" GET/POST variable instedad of 
"redirect_url".


So what's the difference between those 2 methods (except for the different 
spelling of the GET/POST variable) ?
(And if there's no difference, why not remove one of them?)
