Minor fixes
Hello Andri Steiner, dear Ops One team,
i am currently looking for TYPO3 -> Nginx Cache solutions and stumbled across your solution for TYPO3 -> Varnish Cache which i think is a really well template for an Nginx Cache solution. Thank you. I added some minor fixes in this pull request which i recognized during my code lecture. Maybe you want to merge them (not tested though!).
Greetings Alex
