HTTP_E_STATUS_USE_PROXY
HTTP_E_STATUS_USE_PROXY maps to HTTP 305 Use Proxy. RFC 9110 deprecates this status code because of security concerns; modern servers should not generate it and modern clients should not rely on it to configure proxy routing.
What to do
- Inspect the response source and determine whether an obsolete proxy, gateway, or test service generated the status.
- Configure proxies through the operating system, browser, client library, or managed policy instead of trusting a 305 response.
- Check for interception or legacy infrastructure that may be rewriting responses.
