    !!!Now we have to create file like 'configuration.json'. In this file, we will map our microservice URLs with our ocelot application URLs!!!

    The 'Routes' property is an array type where we are going to add our URL mappings.
    The 'DownstreamPathTeplate' is our microservice endpoint.
    The 'DownstreamSchem' is our microservice is 'HTTPS' or 'HTTP'.
    The 'DownstreamHostAndPorts' where we have to define our microservice HostName and PortNumber.
    The 'UpStreamPathTemplate' is ocelot URL which is an alia URL for our 'DownStreamPathTemlate'.
    The 'UpstreamHttpMethod' specifies the supported methods.
