Tinyproxy

Tinyproxy is an open-source HTTP and SSL proxy daemon designed for small network settings and POSIX operating systems. It operates as a server-side daemon that manages web traffic between clients and the internet, focusing on low resource consumption to avoid the overhead associated with larger proxy solutions. This makes it suitable for environments where hardware resources are limited or where a larger proxy would introduce unnecessary security risks.

Network administrators use Tinyproxy to control HTTP requests within a local network or to manage how traffic is routed to external servers. The software is deployed by compiling the source code using a standard GNU configure script and installing it on a compatible operating system. It provides a way to share a single internet connection across a small network while maintaining control over the types of requests allowed to pass through the gateway.

Key features

• Buffering of high speed server responses to match client speeds
• Support for SSL proxying
• Domain and URL filtering to restrict specific web addresses
• Transparent proxy mode for automatic traffic redirection via firewall rules
• Reverse proxying capabilities
• Upstream proxy support for chaining connections through other servers
• XTinyproxy header support for domain identification

The software uses a buffering connection concept to reduce internet sluggishness by storing responses from a server and relaying them to the client at the maximum acceptable speed. This architecture ensures that high speed server responses do not overwhelm slower clients. The build system allows for optional components to be enabled during compilation, such as full debugging support or specific filtering tools, allowing the administrator to tailor the binary to the specific needs of the network. It is intended for users who require a minimal footprint and a straightforward installation process via the automake system.

Tinyproxy is positioned as a lightweight utility for administrators who need basic proxy functionality without high memory or CPU requirements.
