Hi Jonathan,

Thanks for your response.  I need to login/out from a web-based form of 
ISP to enable/disable internet. I'm trying do the same from console with 
curl/wget. Now I have dig more and found following source code when 
logged in, wonder how to use it with curl/wget to call the logout function.

~~~

function logout(){
                var out = confirm ('Do you really want to Logout ?')
                    if(out){
                    document.forms["logoutForm"].submit();
                    }
            }
function logoutbut(){
                var out = confirm ('Do you really want to Logout ?')
                    if(out){
                    document.forms["logoutbut"].submit();
                    }
            }

<form action="logoutUI.do" method="get" name="logoutForm" 
id="logoutForm" style="margin-top: 0px;">
Welcome<b> <USERNAME> </b> &nbsp;
    &nbsp; <a href="javascript:logout();" style="background: 
url(&quot;logout.GIF&quot;) no-repeat;" onmouseover="return 
showStatus('text');">&nbsp;<u>Logout</u>&nbsp;</a>
<input type="hidden" id="SeUserName" name="SeUserName" 
value="<USERNAME>"></form>

here <USERNAME> is provided by the ISP
