[TYPO3-english] Return to 'previous page'

[Tomas Mrozek]

To return to the previous page the TYPO3 needs to know the UID of that 
page for which it has to store it somewhere. I think that there are 
basically 2 options:

1. Pass it as a part of URL - looks bad but probably could be done with 
TS only.

2. Store it as a cookie - you will need to do it with PHP. You don't 
need an extension. Creating one file with a class + method and including 
it in the TS will be enough. Then you can call the method in the TypoScript.

Using JavaScript's "history.go(-1)" is not that good, in my opinion, as 
you won't be able to get additional data of the page (e.g. page title as 
the text for the link) and the link will be useless if the user comes 
from a different website, nevermind the question "Why duplicate 
functions of browser's buttons?"
