HTTP Headers Comparison Tool

Case-Insensitive Comparison

HTTP headers are case-insensitive by specification. Our comparison tool automatically normalizes header names for accurate matching while preserving the original values. This ensures that headers like 'Content-Type' and 'content-type' are treated as identical.
