JsonServiceClient not respecting RedirectHttpHandler response

The JsonServiceClient in ServiceStack is a client for making HTTP requests to JSON-based web services. By default, it follows HTTP redirects automatically and transparently handles the redirects for you. However, in some cases, you may encounter issues where the JsonServiceClient does not seem to respect the HTTP redirects as expected.

Here are a few possible reasons and solutions for the JsonServiceClient not respecting redirects:

1. Custom Redirect Handler: Check if you have set a custom HttpMessageHandler or HttpMessageHandlerFactory for the JsonServiceClient. If you have a custom handler that explicitly handles redirects, it might override the default behavior of the JsonServiceClient. Ensure that you are not using a custom handler that interferes with redirects.

2. HTTP Status Codes: Ensure that the server is returning proper HTTP status codes for the redirects. The standard HTTP redirect status codes are 301 (Moved Permanently), 302 (Found), 303 (See Other), and 307 (Temporary Redirect). Some non-standard status codes, such as 302 with a different method (e.g., POST), may not be automatically followed by the client.

3. Redirection Loop: If the server returns a series of redirects in a loop (e.g., A redirects to B, and B redirects back to A), the JsonServiceClient may stop following redirects after a certain number of iterations (e.g., 20 or 50) to avoid potential infinite loops. Check if your redirects are correctly set up and do not form a loop.

4. Incorrect URL Format: Ensure that the URL used in the JsonServiceClient is correctly formatted and includes the necessary HTTP/HTTPS protocol and the full path. An incorrectly formatted URL might cause the JsonServiceClient to behave unexpectedly.

5. Authentication and Cookies: If your redirects involve authentication or cookies, ensure that the JsonServiceClient handles cookies correctly and includes any necessary authentication tokens in the redirected requests.

6. ServiceStack Version: If you are experiencing issues with redirects, make sure you are using the latest version of ServiceStack. Older versions might have bugs or limitations that are resolved in newer releases.

To troubleshoot the issue further, you can enable tracing or logging in your JsonServiceClient to see the details of the requests and responses, including any redirects. This can help you identify any specific issues or anomalies in the redirect behavior.

If you have ruled out any custom configurations or handlers that might interfere with redirects, and the issue persists, you can consider reporting the problem to the ServiceStack community or support channels for further assistance and investigation.
