bash shell script to serve an http request via inetd

inetd_www.bash

#!/bin/bash
#
# Shell script usable as web "server"
# Code mostly copied from web, my contribution was to add the sanitation.
#

###
### PARSE THE REQUEST
###

# first line is request
read request

# ignore the header
while /bin/true; do
        read header
        [ "$header" == $'\r' ] && break
done

# extract url, path, and query from request
url="${request#GET }"
url="${url% HTTP/*}"
path="${url%%\?*}"
query="${url#*\?}"

# make p_variables out of parameter string
for i in $(echo $query | sed 's/\&/\n/g') ; do
        key=${i%%=*}
        key=$(echo $key | sed 's/[^a-z_]//g')  # sanitize, accept lowercase only + underscore
        value=${i#*=}
        value=$(echo $value | tr -d ';''\001'-'\011''\013''\014''\016'-'\037''\200'-'\377') # sanitize, remove non-printing chars and semicolon
        eval "p_$key=$value"
done

###
### DO THE WORK
###

#
# there are plenty of extant examples for serving a file here
# google for "bash web server", etc.

Do you have anything similar for post requests?

I assume you will have to parse the post request your self, it will be little bit tricky as you need to handle things like multipart.

@thanks,

this is nice, but dont use it in services on the internet. Use it only on a protected network!
