Dear Monks
I am trying to write a cgi perl cgi script that accepts a url like:
&xmin=100&xmax=200&other=parameters&
and return an image.
I am trying but new to cgi programming.
Here is my code. I know its a very very basic code that I have written but I guess its better to try then nothing ;) 
#!/usr/bin/perl 
use CGI;
my $query = new CGI;
my $xmin = $query->param('xmin');
my $xmin = $query->param('xmax');

print "Content-type:text/html\n\n";

print "<html>";



if( $ENV{"REQUEST_METHOD" eq "GET"} )

     {

            ($key, $value) = split(/=/,$ENV{"QUERY_STRING"});

     }

print "<li>Key is \" $key \" ";

print "<li>Value is \" $value \" ";

print "</html>";

I have to actually pass these values to a javascript like this in my html page:- 
function query(x){
           var url = '/MyScript.pl?chr='
           + chr + '&version=5&layers=gene&organism=' + org + '&loc='
           + x + '&' + 'ds=' + 588
           jfetch(url,'query');
         }

My input data can be like this 
Chr1 100  200  cancer  human  
Chr2 300  400  diabetes  human
Chr3 600  700  cough     human
