.TH RC-HTTPD 8
|
||
|
.SH NAME
|
||
|
rc-httpd \- HTTP server
|
||
|
.SH SYNOPSIS
|
||
|
.B rc-httpd/rc-httpd
|
||
|
.SH DESCRIPTION
|
||
|
.I Rc-httpd
|
||
|
serves the requested file or an index of files found under
|
||
|
a website's root directory, or, in the case of CGI, executes
|
||
|
a specified CGI program.
|
||
|
.SH CONFIGURATION
|
||
|
.PP
|
||
|
As all pieces of
|
||
|
.B rc-httpd
|
||
|
are shell scripts, configuration is achieved by setting variables
|
||
|
and adding, removing or modifying commands in various files.
|
||
|
.PP
|
||
|
.B rc-httpd
|
||
|
.PP
|
||
|
.I rc_httpd_dir
|
||
|
must be set to the root of the rc-httpd installation,
|
||
|
the directory containing the rc-httpd script.
|
||
|
.PP
|
||
|
.I path
|
||
|
must include
|
||
|
.I rc_httpd_dir/handlers
|
||
|
ahead of the base system's path elements.
|
||
|
.PP
|
||
|
.I cgi_path
|
||
|
is substituted for
|
||
|
.I path
|
||
|
when cgi scripts are run. (Be sure
|
||
|
to set
|
||
|
.I path
|
||
|
back in rc-based cgi scripts.)
|
||
|
.PP
|
||
|
.I extra_headers
|
||
|
is an optional list of strings to emit when sending http headers.
|
||
|
.PP
|
||
|
.I SERVER_PORT
|
||
|
is the port HTTP is to be served on.
|
||
|
.PP
|
||
|
.B select-handler
|
||
|
.PP
|
||
|
.I PATH_INFO
|
||
|
is the location relative to the website's root directory of the file
|
||
|
to be displayed.
|
||
|
Typically, the
|
||
|
.I location
|
||
|
from the incoming request is honored.
|
||
|
.PP
|
||
|
.I FS_ROOT
|
||
|
sets the root directory of the website.
|
||
|
.PP
|
||
|
.I NOINDEXFILE
|
||
|
instructs the
|
||
|
.B dir-index
|
||
|
module not to
|
||
|
look for
|
||
|
.B index.html
|
||
|
files, otherwise if an
|
||
|
.B index.html
|
||
|
file is found
|
||
|
.B dir-index
|
||
|
will exec
|
||
|
.B serve-static
|
||
|
to serve the file. At present there
|
||
|
is no module to serve an index file but not a directory.
|
||
|
.PP
|
||
|
If you do not want directory indexing at all, replace
|
||
|
.B static-or-index
|
||
|
with
|
||
|
.B serve-static,
|
||
|
which will report 503 forbidden for directories.
|
||
|
.PP
|
||
|
Multiple virtual hosts may be configured by creating conditional
|
||
|
statements that act upon the
|
||
|
.I SERVER_NAME
|
||
|
variable. Fine-grained control of specific request strings may
|
||
|
be configured via a similar method acting upon the
|
||
|
.I location
|
||
|
and/or other variables.
|
||
|
.SH EXAMPLES
|
||
|
The following examples demonstrate possible ways to configure
|
||
|
.BR select-handler.
