jackye1995 opened a new issue, #472: URL: https://github.com/apache/arrow-rs-object-store/issues/472
**Describe the bug** After https://github.com/apache/arrow-rs/pull/7183, the request to IMDS no longer uses the reqwest client directly to make request, but instead now goes through `http.connect(&self.client_options.metadata_options())` where `http` is an `HttpConnector`. Looks like when making a request to IMDS to get credentials, the header is overridden, so original headers like User-Agent set by the user will be dropped. This causes access issue when the IMDS server is behind a corporate firewall. **To Reproduce** ```rust #[test] fn test_issue() { use object_store::client::{ClientOptions, HttpClient}; use http::{Method, HeaderValue}; let options = ClientOptions::new() .with_user_agent(HeaderValue::from_static("my-test-app/1.0")); let reqwest_client = options.client().unwrap(); let http_client = HttpClient::new(reqwest_client); let request = http_client .request(Method::GET, "http://169.254.169.254/latest/meta-data/";) .build() .unwrap(); let has_user_agent = request.headers().contains_key("user-agent"); // fails here assert!(has_user_agent) } ``` **Expected behavior** Should preserve the original headers **Additional context** I will put up a PR later with more details -- This is an automated message from the Apache Git Service.
