Remove trailing slash from http url
Remove trailing slash from http url

This inconsistency has been bugging me:

   ==> smtp://127.0.0.1:1025
   ==> http://127.0.0.1:1080/

so fix it:

   ==> smtp://127.0.0.1:1025
   ==> http://127.0.0.1:1080

This should still be fine:

   ==> smtp://127.0.0.1:1025
   ==> http://127.0.0.1:1080/some/prefix
