I'd like to know how to set a cookie on my home page according to the search engine which sends the contact.  so if the source is google the cookie id would reflect that source as it would yahoo etc.  If it is easier I could also get the info from tagging the requested url:  http;//mysite.com?srce=google

This should help you...

<script language="Javascript">

function SetCookie (name,value,expires,path,domain,secure) {
document.cookie = name + "=" + escape (value) +
((expires) ? "; expires=" + expires.toGMTString() : "") +
((path) ? "; path=" + path : "") +
((domain) ? "; domain=" + domain : "") +
((secure) ? "; secure" : "");
}

if (document.referrer&&document.referrer!="")
{
  document.write('Your referre is - '+document.referrer+'<BR>');
  var expdate = new Date ();
  expdate.setTime (expdate.getTime() + (24 * 60 * 60 * 1000)); // 24 hrs from now
  SetCookie ("pagereferrer", document.referrer, expdate);
}

</script>

Hi venkateshwarr,

I appreciate the info.

I wondered if there was anything I had to do to get this up and running.

My web page looks like this, but a cookie is not being set:

<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script language="Javascript">
function SetCookie (name,value,expires,path,domain,secure) {
document.cookie = name + "=" + escape (value) +
((expires) ? "; expires=" + expires.toGMTString() : "") +
((path) ? "; path=" + path : "") +
((domain) ? "; domain=" + domain : "") +
((secure) ? "; secure" : "");
}
if (document.referrer&&document.referrer!="")
{
Ê document.write('Your referre is - '+document.referrer+'<BR>');
Ê var expdate = new Date ();
Ê expdate.setTime (expdate.getTime() + (24 * 60 * 60 * 1000)); // 24 hrs from now
Ê SetCookie ("pagereferrer", document.referrer, expdate);
}
</script>


</head>

<body bgcolor="#FFFFFF">

</body>
</html>

Thanks and regards,
Jon

Hi venkateshwarr,

I just tried the tagged solution:
SetCookie ("pagereferrer", "http;//mysite.com?srce="+document.referrer, expdate);

This gives the result:
http://mysite.com?srce=http://incomingsite.com

What I need is:
http://incomingsite.com?srce=google

capture the google

Regards,
Jon

I did not test it... try this,

var refrer = document.referrer+"";
var rhost= refrer.split(".");
rhost= rhost[0].split("/");

document.write(rhost[2]);
