<route xmlns="http://camel.apache.org/schema/spring" trace="true">
    <!-- Take some input from the console. -->
    <from uri="stream:in?promptMessage=Enter Something: " />

    <!-- Set the URL that we want to send our REST request to. -->
    <setHeader headerName="ecomp-url">
        <constant>https://localhost:9509/services/search-data-service/v1/search/indexes/gdf/documents/88</constant>
    </setHeader>

    <!-- Set values for some HTTP headers that we want to populate for our reqeust. -->
    <setHeader headerName="X-FromAppId">
        <constant>DataLayer</constant>
    </setHeader>
    <setHeader headerName="X-TransactionId">
        <constant>gdf1</constant>
    </setHeader>

    <!-- Invoke the REST client, using our console input as the content body of our request. -->
