Returns a path handler (see \ref{httpd:path-handlers} for details
about path handlers) for cgi-scripts located in
\semvar{bin-dir}. \semvar{cgi-bin-dir} specifies the value of the
\ex{PATH} variable of the environment the cgi-scripts run in. It defaults
to
``\ex{/bin:\ob{}/usr/bin:\ob{}/usr/ucb:\ob{}/usr/bsd:\ob{}/usr/local/bin}''
but is overwritten by the current \ex{PATH} environment variable at
the time \ex{cgi-handler} ist called. The cgi-scripts are called as
specified by CGI/1.1\footnote{see

specification.}.
\begin{itemize}
\item Various environment variables are set (like
\ex{QUERY\_STRING} or \ex{REMOTE\_HOST}).
\item ISINDEX queries get their arguments as command line arguments.
\item Scripts are handled differently according to their name:
\begin{itemize}
\item If the name of the script starts with `\ex{nph-}', its reply
is read, the RFC~822-fields like ``Content-Type'' and ``Status''
are parsed and the client is sent back a real HTTP reply,
containing the rest of the script's output.
\item If the name of the script doesn't start with `\ex{nph-}',
its output is sent back to the client directly. If its return code
is not zero, an error message is generated.

that provides utilities for interacting with the World-Wide Web.
This includes:
The SUnet web system is a collection of packages of \Scheme code that
provides utilities for interacting with the World-Wide Web. This
includes:
\begin{itemize}
\item A Web server.
\item URI and URL parsers and un-parsers (see sections \ref{sec:uri}
and \ref{sec:url}).
\item RFC822-style header parsers (see section \ref{sec:rfc822}).
\item URI and URL parsers and un-parsers (see Chapters \ref{cha:uri}

any CGI-compliant HTTP server (such as NCSA's httpd, or the S.U.
any CGI-compliant HTTP server (such as NCSA's httpd, or the SUnet
Web server).
\end{itemize}
The code can be obtained via anonymous
ftp\footnote{\ttt{}ftp://ftp-swiss.ai.mit.edu/pub/scsh/contrib/net/net.tar.gz}
and is implemented in \scm, using the system calls and support
procedures of scsh, the \Scheme Shell. The code was written to be
clear and modifiable -- it is voluminously commented and all non-\RnRS
dependencies are described at the beginning of each source file.
\FIXME{We should remove the note to read the source files and insert
the essentials here instead.}
I do not have the time to write detailed documentation for these
packages. However, they are very thoroughly commented, and I strongly
recommend reading the source files; they were written to be read, and
the source code comments should provide a clear description of the
system. The remainder of this note gives an overview of the server's
basic architecture and interfaces.
\subsection{The Scheme Underground Web Server}
The server was designed with three principle goals in mind:
The server has three main design goals:
\begin{description}
\item{Extensibility} \\
The server is designed to make it easy to extend the basic
functionality. In fact, the server is nothing but extensions. There
is no distinction between the set of basic services provided by the
server implementation and user extensions -- they are both
implemented in Scheme, and have equal status. The design is ``turtles
all the way down''.
\item[Extensibility]
The server is in fact nothing but extensions, using a mechanism
called ``path handlers'' to define URL-specific services. It has a
toolkit of services that can be used as-is, extended or built
upon. User extensions have exactly the same status as the base
services.
\item{Mobile code} \\
Because the server is written in \scm, it is simple to use the \scm
module system to upload programs to the server for safe execution
within a protected, server-chosen environment. The server comes with
a simple example upload service to demonstrate this capability.
The extension mechanism allows for easy implementation of new
services without the overhead of the CGI interface. Since the
server is written on top of the Scheme shell, the full set of Unix
system calls and program tools is available to the implementor.
\item{Clarity of implementation} \\
Because the server is written in a high-level language, it should
make for a clearer exposition of the HTTP protocol and the
associated URL and URI notations than one written in a low-level
language such as C. This also should help to make the server easy to
modify and adapt to different uses.
\item[Mobile code]
The server allows Scheme code to be uploaded for direct execution
inside the server. The server has complete control over the code,
and can safely execute it in restricted environments that do not
provide access to potentially dangerous primitives (such as the
``delete file'' procedure.)
\item[Clarity]
I\footnote{That's Olin Shivers (\ex{shivers@ai.mit.edu},
\ex{http://www.\ob{}ai.\ob{}mit.\ob{}edu/\ob{}people/\ob{}shivers/}).
For the rest of the documentation, if not mentioned otherwise,
`I' refers to him.} wrote this server to help myself understand
the Web. It is voluminously commented, and I hope it will prove to
be an aid in understanding the low-level details of the Web
protocols.
The SUnet web server has the ability to upload code from Web clients
and execute that code on behalf of the client in a protected
environment.
Some simple documentation on the server is available.

To run the server, you
need version 0.6.3 or later of \urlhd{http://www.scsh.net/}{scsh}{scsh
from \url{http://www.scsh.net/}}.
Beyond actually running the server, the separate parser libraries and
