How to Parse HTTP Headers Online
Parsing headers is a single paste. Here is the flow.
Paste the raw headers
Copy the header block from your request, response or log and paste it in. The parser reads each line and builds a structured view.
Read the structured output
Find the header you care about by name in the key/value output, with repeated headers grouped so you see every value.
Frequently asked questions
