The difference between URI and URL

 

This question has been asked many times before. But before you down-vote this please allow me to ask it in a slightly different way:

Of the following examples, which are URLs, which are URIs and which are both: 

1. www.example.com

2. //www.example.com

3. http://www.example.com

4. www.example.com/myfolder/mypage.html

5. //www.example.com/myfolder/mypage.html

6. http://www.example.com/myfolder/mypage.html

7. myfolder/mypage.html

8. /myfolder/mypage.html

9. mypage.html

Any comment on which are URNs would also be welcome.

I really think What is the difference between URI, URL and URN? should clarify your question. However, I'll try to answer your question directly..

  • www.example.com

    none

  • //www.example.com

    none

  • http://www.example.com

    URL and URI

  • www.example.com/myfolder/mypage.html

    none

  • //www.example.com/myfolder/mypage.html

    none

  • http://www.example.com/myfolder/mypage.html

    URL and URI

  • myfolder/mypage.html

    none

  • /myfolder/mypage.html

    none

  • mypage.html

    none

    • Hope that helps a little.
