URL with dot causes 404 error

Question

I have an Asp.Net Web Api application which takes ip address as input and return the country of that respective ip. when I pass the below url

http://localhost:portno/xx.xx.xx.xx

it throws Error 404

can any one tell me why?

Answer 1

Short hacky answer: Add a trailing forward slash. IIS thinks it's a file at the end of hte URL.

Longer, more elegant answer: Check out these links for cleaner fixes that require more work:
