How Can I Ensure Proper Credential Passing with HttpClient in a Web Application to Windows Service Communication?

Securing Credential Passing with HttpClient

Communication between a web application and a Windows service using HttpClient sometimes faces challenges in reliably transmitting credentials. While the WebClient class might seem suitable for asynchronous operations, it can lead to inconsistent credential handling.

To guarantee proper credential transfer, directly configure HttpClient as shown below:

<code class="language-csharp">var myClient = new HttpClient(new HttpClientHandler { UseDefaultCredentials = true });</code>

This setup directs HttpClient to automatically use the credentials of the user initiating the request from the web application. This ensures the Windows service accurately identifies the user, allowing for appropriate authorization based on those credentials.
