[TYPO3-commerce] a-tag parameter for LINKTOPUTINBASKET-Marker

[Sebastian Stanger]

Hi list,

Ich tried to add a rel=nofollow to the LINKTOPUTINBASKET-Marker, sothat 
this link is not indexed by search engines.

The problem is, that these pages a creating a lot of duplicate content, 
with different URL-paramenters and different carts.

Is there a solution for adding the rel=nofollow into the a-tag for this 
link?

I tried to add the following in TS-setup, but did not get the correct 
result:

lib.tx_commerce.articles.addToBasketLink.ATagParams = rel=nofollow


Is there a solution for this?
A workaround would be a restriction of the cart via robots.txt, but 
implementing both would be much better, as some search-engines do not 
really care about robots.txt

Are there any solutions out there?

Kind regards,

Sebastian
