HTTP Scoop is an HTTP protocol analyser, a.k.a. "HTTP sniffer". It passively captures HTTP conversations and presents their details in real-time.

• Use to debug Web scripts/applications
  
• View responses as hex, text (syntax-highlighted for XML/HTML) or as images
  
• Any browser or server technology - no proxy needed
  
• View headers, parameters and POST data
  
• Save responses to disk
