Lightbulb Netcat ( nc -l ) as webserver

Dear Linux guru's

I am trying to create a webserver using nc (netcat only) on RHEL 7.2 running on bash shell.

now the easy thing is to get nc listing to a port and respond back

Code:
$ while true; do { echo -e 'HTTP/1.0 200 OK\r\n'; set; } | nc -l 7877; done

This when called from a browser: http://My-server:7877 I get my env variables. Works perfect !! Love it Smilie

Now when I try http://My-server:7877?asd=1&something=2&other=hello

I was hopping to get QUERY_STRING env variable with all the values sent via browser GET method ! . However the env variable is not set. There is not variable set with these values.


Versions:

Bash
GNU bash, version 4.2.46(1)-release (x86_64-redhat-linux-gnu)

nc
Ncat: Version 6.40 ( Ncat - Netcat for the 21st Century )

redhat
Red Hat Enterprise Linux Server release 7.2

Dont want to use anything other than nc. Cannot install any tool or webserver or binaries. Please dont suggest that

And thanks all for reading my question Smilie.

mrtg-webserver - hints for web server configuration SYNOPSIS
If you want people to actually see the results of your network monitoring efforts you will need a webserver. This document lists some configuration hints for webservers. Contributions welcome. APACHE
Configuring mod_expire A big issue with mrtg monitoring data is the expiry time. All these nice graphs you can create are only valid for a short time. If you do not take special action some webbrowsers will not notice this and you may end up with people seeing old data because of caching issues. The apache module mod_expire allows you to setup special expiry properties for individual file. Here is an example for how this may look for an mrtg web directory. The configuration directives can be stored into a .htaccess file. ############################################################ # Example .htaccess for use with apache-1.2 and mod_expire. # (mod_expire come with apache-1.2 but you have to explicitly # activate it when compiling the httpd ...) ############################################################# # <Files "*-day.png"> ExpiresActive On # enable expirations # five minutes ExpiresDefault M300 </Files> <Files "*-week.png"> ExpiresActive On ExpiresDefault M1800 </Files> <Files "*-month.png"> ExpiresActive On ExpiresDefault M7200 </Files> <Files "*-year.png"> ExpiresActive On ExpiresDefault M86400 </Files> <Files "*.html"> ExpiresActive On ExpiresDefault M300 </Files> # index.html is not automatically generated <Files "index.html"> ExpiresActive Off </Files> AUTHOR
