In TypoScript exists the possibility to get the environment variable HTTP_COOKIE_VARS (which is deprecated):
10 = TEXT
10.data = global : HTTP_COOKIE_VARS | some_cookie
I got this from the documentation.
But on my server (PHP 5.3) this variable is empty! I suppose this is because this environment variable is deprecated. Now I am running out of options, without using an extension, user function or user condition.
Maybe you have an idea! Thanks in advance.
this should do the job (at least with TYPO3 4.5 and PHP 5.3.8):
10 = TEXT
10.data = global:_COOKIE|some_cookie
10.wrap = <h2>Cookie: |</h2>
