## Description

SpoofDPI is a network application and local proxy server designed as an anti-censorship tool. It functions as a deep packet inspection circumvention proxy that fragments and modifies outbound HTTP requests to evade network filters and censorship.

The project achieves this by implementing HTTP request fragmentation, splitting single requests into multiple smaller packets to confuse firewalls. It also performs TCP stream manipulation and network traffic obfuscation to hide the nature of web requests and bypass regional content blocks.

The system includes capabilities for transparent network forwarding and file-based configuration management to coordinate how network traffic is handled.
