Managing Gopher and WWW Services
What can we say about the World Wide Web? Your users probably argue that they really
need it to do their jobs. There is a vast wealth of information stored on machines
connected the Internet. The graphical interfaces of browsers and web pages make it
much easier to access and digest this information. Along with this ease can come
problems. World Wide Web (WWW) services allow for the transfer of a wide variety of
file types and for running a number of different programs. This complexity means a
greater potential for problems, especially in terms of security. These services are generic
file transfer mechanisms and require logging and access control consistent with FTP and
terminal services.
The HTTP proxy and authenticating HTTP proxy included with the Gauntlet Firewall
securely handles requests for information via hypertext, Gopher, and file transfer. The
proxy supports hypertext transfer via the HTTP, SHTTP, and SSL protocols; Gopher
transfer via Gopher and protocols; and file transfer via FTP.
This chapter explains the concepts behind the HTTP proxy and how it works; how to
configure the proxy for web services, Gopher services, and file transfer services; and how
to configure these services to run through the firewall. In addition, it includes
information on running HTTP and Gopher servers.
Understanding the Proxy
The Gauntlet HTTP proxy is an application-level proxy that provides configurable access
control and logging mechanisms. The HTTP proxy, which runs on the firewall, passes
HTTP, SHTTP, SSL, and Gopher requests, and FTP URLs and selectors through the
firewall, using rules you supply. You can configure the proxy to allow connections based
on
