Mallet, a framework for creating proxies

This blog post introduces Mallet, a Netty-based framework for building customizable proxies to analyze non-HTTP and HTTP/HTTPS traffic. It explains how to assemble protocol handler pipelines, enable interception and modification (including TLS man-in-the-middle via autogenerated certificates), and aggregate HTTP messages for easier analysis. The post walks through creating SOCKS-based TCP relays, adding SSL server/client handlers, implementing HTTP proxying with codecs and aggregators, and extending behavior using scriptable or pre-existing Netty handlers.
