Open Source C Proxy Servers

UFTP is an encrypted multicast file transfer program, designed to securely, reliably, and efficiently transfer files to multiple receivers simultaneously. This is useful for distributing large files to a large number of receivers, and is especially useful for data distribution over a satellite link (with two way communication), where the inherent delay makes any TCP based communication highly inefficient. The multicast encryption scheme is based on TLS with extensions to allow multiple receivers to share a common key. UFTP also has the capability to communicate over disjoint networks separated by one or more firewalls (NAT traversal) and without full end-to-end multicast capability (multicast tunneling) through the use of a UFTP proxy server. These proxies also provide scalability by aggregating responses from a group of receivers.

c-icap is an implementation of an ICAP server. It can be used with HTTP proxies that support the ICAP protocol such as the Squid 3.x HTTP proxy server to implement content adaptation/filtering services.

This program allows you to use SSH, TELNET, VNC, FTP and any other Internet application from behind HTTP(HTTPS) and SOCKS(4/5) proxy servers. This "proxifier" provides proxy server support to any app.

nuster is a high-performance HTTP proxy cache server and RESTful NoSQL cache server based on HAProxy. It is 100% compatible with HAProxy and takes full advantage of the ACL functionality of HAProxy to provide a fine-grained caching policy based on the content of request, response or server status. nuster can be used as an HTTP/TCP load balancer just like HAProxy. nuster can also be used as a RESTful NoSQL cache server, using HTTP POST/GET/DELETE to set/get/delete Key/Value objects. It can be used as an internal NoSQL cache that sits between your application and a database like Memcached or Redis as well as a user-facing NoSQL cache that sits between the end-user and your application. It supports headers, and cookies, so you can store per-user data to the same endpoint.
