Hello
I have small pdf search site searches pdf over internet when somebody search URL look like www.mypdfsearchwebsite.com/pdf/nginx.html with (html extension)

google index this address with html and without html version so there are duplicate record on google index each search lies without html www.mypdfsearchwebsite.com/pdf/nginx and with html www.mypdfsearchwebsite.com/pdf/nginx.html version

what i would like to do is if i can make it around without html version (www.mypdfsearchwebsite.com/pdf/nginx) will be returned 404 page rather than 200 it could be also jail /pdf/ directory only allow html if html couldn't find go to nginx 404 page.

I am not nginx guru but the newbie if you send me exactly location where i put suggested code i would be highly appreciated

thank you very much for your help
