controller=404 and bingbot

[patrmich]

Hi,

In the Apache log file of my server, I can see many lines like this :

www.myshop.com 157.55.39.89 - - [08/May/2017:19:26:53 +0000] (0 s) "GET /one-page-of-my-shop.html?controller=404 HTTP/1.1" 404 88900 "-" "Mozilla/5.0 (iPhone; CPU iPhone OS 7_0 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) Version/7.0 Mobile/11A465 Safari/9537.53 (compatible; bingbot/2.0; +http://www.bing.com/bingbot.htm)"

157.55.39.89 is an IP coming from Microsoft bingbot

However the following page is a fully working page of my shop :
www.myshop.com/one-page-of-my-shop.html

So, I do not understand why bingbot adds "?controller=404" at the end of a valid url, and then try to browse such a page.


I thank you in advance for any suggestion.
