I am trying to consume a third party REST API using Spring's RestTemplate component. I have tried entering the same request on an external REST API Client (Postman) - using the same URI and custom headers and I am able to retrieve the correct data.

However, when I tried to mirror the exact request using RestTemplate, it returns me 

```
        <html><head>
        <title>302 Found</title>
        </head><body>
        <h1>Found</h1>
        <p>The document has moved <a href="https://address/{path of endpoint}">here</a>.</p>
        <hr>
        <address>Apache/2.4.7 (Ubuntu) Server at address Port 80</address>
        </body></html>

```

This is a sample of the code I am using:

```
        String uri = "http://address/{path of endpoint}";
        RestTemplate restTemplate = new RestTemplate();
        HttpHeaders headers = new HttpHeaders();
        headers.set(someCustomHeaderKey, someCustomHeaderValue);
        HttpEntity<String> entity = new HttpEntity<String>(headers);
        ResponseEntity<String> response = restTemplate.exchange(uri, HttpMethod.GET, entity, String.class);

```

I have read that java does not allow redirect from one protocol to another, for instance, from http to https and vise versa. Would require some help on the approach on this.
