prototype.js + POST ajax.request

[DrDankWD]

I am having some trouble with an ajax request using prototype.js.  Basically I had a function that save some content to the database, the problem started when the amount of content was exceeding the character limit of GET.  So i switched the 'method' to POST. But now I am getting a 406 Not Acceptable error when trying to make the request.

 

Here is the ajax request:

 

function saveEditPage(page_id)
{
var url = 'ajax/prTreeAjax.php?action=saveEditPage';
var pars = '';
pars += 'page_id=' + page_id;
pars += '&title=' + escape(document.getElementById('edit_page_title').value);
pars += '&description=' + escape(document.getElementById('edit_description').value);

var myAjax = new Ajax.Request(
	url, 
	{
		method: 'post', 
		parameters: pars, 
		onComplete: getMessageResponse
	});


function getMessageResponse(originalRequest)
{			
showPage(page_id);
}

}

 

Anyone have any ideas as to why I am getting the 406 error when using the POST method?  When I use GET it works fine (other than not allow for the large amount of text to be sent).

 

Thanks,

Well I have narrowed it down to the server environment.  Same code works fien on a cpanel/whm server.  The box its currently on is a Plesk server that has been nothing but trouble.
