    % package require http
    2.5.1
    % set url "http://www.slashdot.org/"
    http://www.slashdot.org/
    % set apache "Apache"
    Apache
    % set id [::http::geturl $url]
    ::http::1
    % set data [::http::data $id]

    % regexp "$apache" $data match

    % puts "$match"
    Apache
    % exit

Apla, anti gia {$apache} sto regexp perasa ws pattern to "$apache",
kai to $apache egine interpolate mesa sto match pattern.
