if r.URL.Path == "/health" {
return false // skip logging for health endpoint
}
if r.PathValue("secretToken") != "" {
// obfuscate secret token in the request path
newPath := strings.ReplaceAll(r.URL.Path, r.PathValue("secretToken"), r.PathValue("secretToken")[:4]+"****")
r.URL.Path = newPath
}
return true // log the request
