Rails spinoffs - Aug 2007 - prototype.js throwing 406 - Not Acceptible on page access

I''m just getting started with prototype.js...well, started is not
quite the word.
Let me rephrase. I''m just beginning to be frustrated and driven crazy
by prototype.js.

Trying to set up a session id, I developed a cgi responder on
my site which returns an id when requested.

My cgi responder specifies Content-Type: text/xml; charset="UTF-8"
when
it returns the response and when I use wgat on that responder I see...

HTTP request sent, awaiting response... 200 OK
Length: unspecified [text/xml]

Here is what the responder is sending right now.
--------content sent-----------
<?xml version="1.0" encoding="UTF-8"?>
<session>
<id>hi!there</id>
<key>unlock</key>
</session>
--------------------

I cannot see a problem in the served page, yet prototype throws an
exception ''Error 406 -- Not Acceptable''.

Here is the code I''m using to make the request:

var source = ''http://mysite.com/cgi-bin/feedit.cgi'';
var opt = {
			asynchronous: false,
			parameters: {p: ''st''},
			onComplete: handleXMLFunc,
			// now the errors
			onException: function(e, x) { alert(''exception: ''+x);
throw(x) },
			on404: function(t) {
				alert(''Error 404: location
"''+t.statusText+''" not found.'');
			},
			onFailure: function(t) {
				alert(''Error '' + t.status + '' -- '' +
t.statusText);
			}
		};

var myAjax = new Ajax.Request( source, opt );

Anyone see (or have theories about) what I''m doing wrong?

ANSWER FOUND!

I had altered my code (shown above) to upload here, but the real
parameter value I was
using for testing was ''p=start''.

''START'' turns out to be a magic word that SecFilter is going
to choke
on. That makes sense as it is, actually,
a magic word on most systems.

When I changed the code to use param p=st (just like I''d said I was
using), the 406 error went away.

Even so, I guess this is a useful lesson for anyone when deciding what
to use as submit values -- stay away from ''start'' and probably
other
things like ''kill'' or ''sudo'', etc.
