/index.php?main_page=product_info

Is this supposed to lead somewhere? on my site it delivers
Sorry, the product was not found.

I ask because a user submited that they got to this website, but ive tripple checked every link on the site and they work fine, however im thinking maybe it was linked from a third party site to a older product, but the url /index.php?main_page=product_info seems like it should so something, no?

Probably got mis copied as a cpath is required as in

index.php?main_page=product_info&cPath=1_4

index.php?main_page=product_info does not lead to any product nor any page as it is looking for product info for???

so i just should just ignore it, how would someone get there

Like I stated - probably a mis-copied/truncated link
