What I've done with my httpd code (and it might not be the best way to do it)
was to actually output some Javascript code that accesses the document object
normally. 

I actually got this Javascipt from some JS help page... author unknown.

<script language="JavaScript">
<!--

// Use this function to retrieve a cookie.
function getCookie(name){
var cname = name + "=";
var dc = document.cookie;
    if (dc.length > 0) {
    begin = dc.indexOf(cname);
        if (begin != -1) {
        begin += cname.length;
        end = dc.indexOf(";", begin);
            if (end == -1) end = dc.length;
            return unescape(dc.substring(begin, end));
        }
    }
return null;
}

// Use this function to save a cookie.
function setCookie(name, value) {
document.cookie = name + "=" + escape(value) + "; path=/";
}

// Use this function to delete a cookie.
function delCookie(name) {
document.cookie = name + "=; expires=Thu, 01-Jan-70 00:00:01 GMT" +  "; path=/";
}
//-->
</script>

I spit the Javascript out first then I call something like:

send_html_output("<script language="JavaScript">);
send_html_output("setCookie(\"ACCOUNTNAME\", account_name);");
send_html_output("setCookie(\"PASSWORD\", encrypted_password);");
send_html_output("</script>");

Then show other HTML stuff.

I haven't used this in any sort of production code so there may be serious 
flaws in the way I handle this. It worked for me though. :)

Good luck!
