=item B<http_proxy>  the url of the http proxy

=item B<https_proxy> the url of the https proxy

=item B<ftp_proxy>   the url for the ftp proxy

=head3 INPUT

    $self: this object

    $proxy: the hash containing what returns from getVarFromSh

=head3 DESCRIPTION

    This method returns true if the each value match
    certain conditions like the leading http:// for http proxy
    or https:// for the https proxy, etc.

    $proxy is passed by reference thus $proxy->{no_proxy} value
    is sanitized (trimmed).
