problems with ajax

Actually , the content-length header is not required [rfc]. By eliminating it you can also eliminate the need for 'Connection: close', making the whole thing just that little bit shorter. :lol:

Code:

if (parameters) {
    xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
}
xmlhttp.send(parameters || null);

I still suggest wrapping it up nicely [example]. You only have to do it once, and then you can forget about it.
