Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

How can I pass the URL within query string together and translate the double quote into CGI-encoded quote characters. such as http://www.server.com/index.pl?q="att+dsl" became http://www.server.com/index.pl?q=%22att+dsl%22 within URL, how?

    Here's one way: 

      use URI::Escape;
  my $url = 'http://www.server.com/index.pl?' . uri_escape('q="att+dsl
+"');

    As you may already use CGI; you can do it with (updated, thanks to echo):

    my $escaped_url = $url . CGI::escape($query_string);

      Be careful not to escape the whole URL though, you want to leave those slashes intact. Only the query string itself should be escaped.

      If you are already parsing the parameters with CGI it does it automatically.

      I tend to do $cgi->Vars() which returns a hash of all parameters to the script. It returns the parameters of the query string if it is a GET or the form if it is a POST. I wrote a little test script:

      #!/usr/bin/perl 

use CGI;
my $cgi = new CGI;
my %form = $cgi->Vars();

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

foreach my $key(keys %form) {
    print "$key = $form{$key}<br>\n";
}
print "</body></html>\n";
exit;

      I fed it this url:
      urltest.cgi?param=%22something%22¶m2=something_else

      It printed "something" something_else. The point is that CGI will handle this automatically.

        If you reread the question, you will see, that Anonymous Monk asked for tips to ENCODE the query string...
