Frequently Asked Questions
Can this parse both requests and responses?
Yes. It detects request lines and response status lines, then normalizes header key-value pairs into one structure.
What happens to duplicate headers?
Current output keeps the latest value for duplicate keys. For advanced multi-value handling, expand parser logic as needed.
Is this useful for API debugging?
Yes. It helps quickly inspect and copy header data when troubleshooting auth, content negotiation, or proxy issues.
