It's shareware and binary-only. I'd rather have free software with source code.

Take a look at Pound (<a href="http://www.apsis.ch/pound/" rel="ugc">http://www.apsis.ch/pound/</a>). I think it will do what you are looking for.

hm, Varnish looks promising -- <a href="http://varnish.projects.linpro.no/" rel="ugc">http://varnish.projects.linpro.no/</a><br />
nginx could be hacked, too (http_sub_module looks promising), but at the moment I don't have time for this.

I am looking for a replacement to Orenosp (<a href="http://www.orenosv.com/orenosp_en.html" rel="ugc">http://www.orenosv.com/orenosp_en.html</a>), a shareware reverse proxy server for Linux. Its main selling points were:<br />
<br />
- standalone<br />
- single https frontend with name-based virtual host support<br />
- multiple http/https backends<br />
- persistent connections to backends<br />
- header (incoming and outgoing) and content rewriting with multiple rules<br />
<br />
I have looked at yxorp, nginx, apache mod_proxy, squid. &nbsp;Neither of them does all of the above.

Standalone reverse proxy with support for content rewriting

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Software Firewalls

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.

Linux Networking

A web server refers to the software that helps to deliver web content that can be accessed either through the Internet or through an intranet. The primary function of a web server is to store, process and deliver web pages to clients. The communication between client and server takes place using the Hypertext Transfer Protocol (HTTP). The most common use of web servers is to host websites, but there are other uses such as gaming, data storage, running enterprise applications, handling email, FTP, etc.
