[TYPO3-english] How to store HTTP_REFERER in session

[Morten Kjems]

Hi I want to store the HTTP_REFERER in a session so I can display 
content based on where the user came from before visiting my site.

I found the handy extension 'Session' that lets you store values in a 
session.

http://typo3.org/extensions/repository/view/session

If I store a static value like below there is no problem and I can 
output the value and create conditions based on it.


page.20 < lib.setSessionVar
page.20.userFunc {
	name = referer
	value = staticvalue
	}


But when I try to store the HTTP_REFERER like below. Then my entire page 
rendering is broken.


page.20 < lib.setSessionVar
page.20.userFunc {
	name = referer
	value = TEXT
	value.data = getenv:HTTP_REFERER
	}

What am I doing wrong?

All suggestions are most welcome.

Regards
