[eric lin <fsshl@centurytel.net>]

Dear webmaster of debian or any linuxer:

   I had a site using html
it seem for me form only can have one action , I need more than one, 
both record data and also send visiter or another page ,

  now I see some you your website 's source code it use form 
action="user.php or serarch.php"

   what is that can achieve two actions?

  I used tradition
"http://www.abc.com/cgi-bin/entrance.cgi";

  in my /usr/lib/cgi-bin/  directory, it contain entrance.cgi with one 
sace character in it, I especially make it as chmod 777 and the 
directory /usr/lib/cgi-bin

  but when I hit the submit bottom
