When I wanted to fetch a certain page with htm extension I noticed an attachment after the htm extenstion http://www.example.com/IP_814.htm#.Uk1_MtKsh8E Google could not fetch this page it gave the 502 error code.
When I fetched the same page as http://www.example.com/IP_814.htm Google fetched it and gave me the green check.
When I created the page, I named it IP_814 with extension htm as this is a individual internal product page. I believe that the code or number behind the htm changes daily.
What should I do so Google crawls my individual product pages with the htm extension?
