Burp Request Minimizer

A high-performance Burp Suite Extension written in Python. It is designed for bug bounty hunters and penetration testers to automate the minimization of HTTP requests.

🚀 Key Features

• ⚡ Multi-Threaded: Runs in a background thread with a dedicated Swing UI (Progress Bar + Stop Button) so it never freezes Burp Suite.
• 🍪 Binary Search for Cookies: Uses a "Block Dropping" algorithm to minimize large cookie jars in $O(\log N)$ time, significantly faster than linear removal.
• 🔗 Combined Mode: A single click ("Minimize EVERYTHING") chains header removal and cookie minimization, handling baseline refreshes between phases automatically.
• 🛡️ Smart Comparison: accurately compares responses using:
  • Status Code (Exact Match)
  • Content-Type (Exact Match)
  • Content-Length (Smart Tolerance: ±10% for large bodies, ±20 bytes for small JSON).

🛠️ Installation

Prerequisites

1. Burp Suite (Community or Professional).
2. Jython Standalone JAR (Required to run Python extensions).
   • Download: Jython Standalone

Steps
