'URL' section for custom local repo on satellite 6.2

When we create a custom local repo on satellite server 6, what do we suppose to put on "URL" section on Web UI under the "Product" --> Repositories --> Custom repo --> URL ( under Type ) to sync the custom rpms. I know on Spacewalk, it was soemething like "file:///custom repos/.." . ( I am not trying to sync external repos here, custom repositories are created on Satellite Server )
