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.

URI::URL(3)						User Contributed Perl Documentation					       URI::URL(3)

NAME
URI::URL - Uniform Resource Locators SYNOPSIS
$u1 = URI::URL->new($str, $base); $u2 = $u1->abs; DESCRIPTION
This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to be distributed with the libwww-perl library. The following differences exist compared to the "URI" class interface: o The URI::URL module exports the url() function as an alternate constructor interface. o The constructor takes an optional $base argument. The "URI::URL" class is a subclass of "URI::WithBase". o The URI::URL->newlocal class method is the same as URI::file->new_abs. o URI::URL::strict(1) o $url->print_on method o $url->crack method o $url->full_path: same as ($uri->abs_path || "/") o $url->netloc: same as $uri->authority o $url->epath, $url->equery: same as $uri->path, $uri->query o $url->path and $url->query pass unescaped strings. o $url->path_components: same as $uri->path_segments (if you don't consider path segment parameters) o $url->params and $url->eparams methods o $url->base method. See URI::WithBase. o $url->abs and $url->rel have an optional $base argument. See URI::WithBase. o $url->frag: same as $uri->fragment o $url->keywords: same as $uri->query_keywords o $url->localpath and friends map to $uri->file. o $url->address and $url->encoded822addr: same as $uri->to for mailto URI o $url->groupart method for news URI o $url->article: same as $uri->message SEE ALSO
