🔴 High importance

Issue: The 'res.Body.Close()' call should be deferred immediately after the 'res, err := frontendClient.Do(getReq)' call to ensure that the response body is closed even if an error occurs later in the function.

Fix: Defer the 'res.Body.Close()' call immediately after the 'res, err := frontendClient.Do(getReq)' call to ensure the response body is closed properly.

🔴 High importance

Issue: The defer statement to close the response body is placed after a potential early return due to an error check. This means that if an error occurs, the response body will not be closed, leading to a resource leak. A similar issue was also found in src/net/http/httputil/reverseproxy_test.go (line 806).

Fix: Move the defer statement to close the response body immediately after the response is received, before any error checks.
