How to Ensure Headers Are Received in HttpURLConnection Requests?

Troubleshooting Header Addition in HttpURLConnection

When attempting to append headers to an HttpURLConnection request, the setRequestProperty() method may not always function as expected, leading to the server not receiving the intended headers.

One potential solution, which has proven effective in TomCat environments, is to utilize the following code snippet:

URL myURL = new URL(serviceURL);
HttpURLConnection myURLConnection = (HttpURLConnection)myURL.openConnection();

String userCredentials = "username:password";
String basicAuth = "Basic " + new String(Base64.getEncoder().encode(userCredentials.getBytes()));

myURLConnection.setRequestProperty ("Authorization", basicAuth);
// Adjust these properties based on request type (POST/GET) and other requirements
myURLConnection.setRequestMethod("POST");
myURLConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
myURLConnection.setRequestProperty("Content-Length", "" + postData.getBytes().length);
myURLConnection.setRequestProperty("Content-Language", "en-US");
myURLConnection.setUseCaches(false);
myURLConnection.setDoInput(true);
myURLConnection.setDoOutput(true);

This code is specifically designed for POST requests, but you can easily modify it for GET or other request types if necessary. By applying these updates, you should be able to successfully add headers to your HttpURLConnection requests and ensure that the server receives the expected headers.
