<code>

function getHttpRes()

alert(http.readyState);
if(http.readyState == 4)
{
var res = http.responseText;
alert(res);
/*
if(res)

I know I need to cleanup the browser type function, but for whatever reason I cannot get a value for readyState. The exception is always "undefined" and I always get it 4 times. I've tried this many different ways and I'm pulling my hair out. I can get readyState if I use GET. Using FF 3.5.6 and kubuntu 9.10. Any suggestions.

Looks like "http" is out of scope by the time you get to getHttpRes. Have you tried making it global?

Damn, I feel like an idiot. I guess this is what happens when you stare at your code for too long 🙁. Thanks.
