Permalink issue

Help
1

Hi,

 I have created a page in Jekyll. and added a first permalink as mentioned below 

 1. http://test.com/blogs (not working. showing directory listing)
 2. http://test.com/blogs/blog1 (working)

  for the second link i have added the below line to generate the links
   
           defaults:
               -
                 scope:
                   path: ""      # empty string for all files
                   type: posts   # limit to posts
                 values:
                   is_post: true # automatically set is_post=true for all posts
                   permalink: "/blogs/:title"

which is working fine and for first link when i visit it is showing directory. is there any way that the first links should also work? i want the first URL to work.

please help.

Thank you,
