*
* Typical usage:
* for non root user
* httpd -p 8080 -h $HOME/public_html
* or for daemon start from rc script with uid=0:
* httpd -u www
* This is equivalent if www user have uid=80 to
* httpd -p 80 -u 80 -h /www -c /etc/httpd.conf -r "Web Server Authentication"
*
*
* When a url contains "cgi-bin" it is assumed to be a cgi script. The
* server changes directory to the location of the script and executes it
* after setting QUERY_STRING and other environment variables. If url args
* are included in the url or as a post, the args are placed into decoded
* environment variables. e.g. /cgi-bin/setup?foo=Hello%20World will set
* the $CGI_foo environment variable to "Hello World" while
* CONFIG_FEATURE_HTTPD_SET_CGI_VARS_TO_ENV enabled.
*
* The server can also be invoked as a url arg decoder and html text encoder
* as follows:
* foo=`httpd -d $foo` # decode "Hello%20World" as "Hello World"
* bar=`httpd -e "
* Note that url encoding for arguments is not the same as html encoding for
* presenation. -d decodes a url-encoded argument while -e encodes in html
* for page display.
*
* httpd.conf has the following format:
*
* A:172.20. # Allow any address that begins with 172.20
* A:10.10. # Allow any address that begins with 10.10.
* A:10.20 # Allow any address that previous set and 10.200-209.X.X
* A:127.0.0.1 # Allow local loopback connections
* D:* # Deny from other IP connections
* /cgi-bin:foo:bar # Require user foo, pwd bar on urls starting with /cgi-bin/
* /adm:admin:setup # Require user admin, pwd setup on urls starting with /adm/
* /adm:toor:PaSsWd # or user toor, pwd PaSsWd on urls starting with /adm/
* .au:audio/basic # additional mime type for audio.au files
*
* A/D may be as a/d or allow/deny - first char case unsensitive
* Deny IP rules take precedence over allow rules.
*
*
* The Deny/Allow IP logic:
*
* - Default is to allow all. No addresses are denied unless
* denied with a D: rule.
* - Order of Deny/Allow rules is significant
* - Deny rules take precedence over allow rules.
* - If a deny all rule (D:*) is used it acts as a catch-all for unmatched
* addresses.
* - Specification of Allow all (A:*) is a no-op
*
* Example:
* 1. Allow only specified addresses
* A:172.20. # Allow any address that begins with 172.20
* A:10.10. # Allow any address that begins with 10.10.
* A:10.10 # Allow any address that previous set and 10.100-109.X.X
* A:127.0.0.1 # Allow local loopback connections
* D:* # Deny from other IP connections
*
* 2. Only deny specified addresses
* D:1.2.3. # deny from 1.2.3.0 - 1.2.3.255
* D:2.3.4. # deny from 2.3.4.0 - 2.3.4.255
* A:* # (optional line added for clarity)
*
* If a sub directory contains a config file it is parsed and merged with
* any existing settings as if it was appended to the original configuration
* except that all previous IP config rules are discarded.
*
* subdir paths are relative to the containing subdir and thus cannot
* affect the parent rules.
*
* Note that since the sub dir is parsed in the forked thread servicing the
* subdir http request, any merge is discarded when the process exits. As a
* result, the subdir settings only have a lifetime of a single request.
*
*
* If -c is not set, an attempt will be made to open the default
* root configuration file. If -c is set and the file is not found, the
* server exits with an error.
