Strange Behavior When Using Java 11's HttpClient with Redirect Handling
I need some guidance on I've encountered a strange issue with I'm converting an old project and I'm working on a personal project and I'm experiencing unexpected behavior while using Java 11's `HttpClient` for making HTTP requests... Specifically, when I set the `followRedirects` option to `HttpClient.Redirect.NORMAL`, I'm expecting that the client will automatically handle 3xx responses and redirect to the new location. However, I noticed that the response for some endpoints is not being followed, even when the `Location` header is present. Here’s the setup I used to create the client: ```java HttpClient client = HttpClient.newBuilder() .followRedirects(HttpClient.Redirect.NORMAL) .version(HttpClient.Version.HTTP_2) .build(); ``` Then, I made a simple GET request: ```java HttpRequest request = HttpRequest.newBuilder() .uri(URI.create("http://example.com/redirected-endpoint")) .GET() .build(); HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString()); System.out.println(response.statusCode()); System.out.println(response.body()); ``` In my case, the endpoint at `http://example.com/redirected-endpoint` returns a `301 Moved Permanently` status code, but instead of following the redirect, I get the response printed with the 301 status code. I've confirmed that the `Location` header is present and correctly points to the new URL. To troubleshoot, I’ve tried setting the `followRedirects` option to `HttpClient.Redirect.ALWAYS`, but that doesn't seem to change the behavior. Additionally, I checked if other requests from the same URL are redirecting correctly; they are. I also ensured that there are no networking issues or firewalls that could be interfering. Has anyone encountered this question or have insights into what might be going wrong? Is there a known scenario with redirect handling in this version of `HttpClient`? I'm working with Java in a Docker container on Ubuntu 22.04. Any advice would be much appreciated. I'm working on a microservice that needs to handle this. Cheers for any assistance! The stack includes Java and several other technologies. I'm developing on macOS with Java. I've been using Java for about a year now. Is there a simpler solution I'm overlooking?
