Terminal API handles 308 responses by redirecting to the correct regional endpoint #1540

This PR introduces a new property enable308Redirect (default true) to let developers opt out and disable the redirect logic. In this case the SDK returns an exception HttpClientException instead.

Summary of Changes

Hello @gcatanese, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the Terminal API client by providing a new configuration option that allows users to explicitly disable the automatic following of HTTP 308 Permanent Redirects. This change gives developers more granular control over network behavior, enabling them to handle 308 responses as exceptions rather than automatic redirections, which can be crucial for specific integration patterns or debugging scenarios.

Highlights

  • New Configuration Option: Introduced enable308Redirect property (default true) in the SDK's configuration, allowing developers to control the handling of HTTP 308 Permanent Redirect responses.
  • Customizable 308 Redirect Behavior: When enable308Redirect is set to false, the SDK will no longer automatically follow 308 redirects. Instead, it will throw an HttpClientException with the 308 status code, providing more explicit control over redirect handling.
  • Enhanced Error Handling: The HttpClientException now includes a more descriptive message when a parsing error occurs, indicating the HTTP status code and the problematic response body.
  • Redirect Loop Prevention: Implemented logic to prevent infinite redirect loops by disabling further redirects for subsequent requests that are initiated as a result of a 308 redirect.

Code Review

This pull request introduces a new configuration option enable308Redirect to allow disabling the automatic 308 redirect handling in the Terminal API. The changes look good overall, and the new functionality is covered by a new test case. I have one suggestion to improve code clarity and remove redundancy in how the default value for the new option is handled.
