wrong URL generated by AjaxUpdater

Description

I use prototype AjaxUpdater to expand items in a tree. As there is the need to submit the path (multiple parents) of the node to be opened and the parent node the URL looks like this:

http://admin.localhost/backend.view=menu&open=/sb2.localhost::sb/philosophie&subjectnode=/sb2.localhost::sb/philosophie

As you can see, i'm using mod_rewrite to expand 'backend.' to the real script with basic parameters, perhaps that's what puzzles prototype. The URL used by AjaxUpdater then looks like this, leading to a 'URL too long' fault of apache:

The error occurs after i switched from Prototype 1.5.0_rc1 to 1.5.0, the code generating the url in my script is the same, and it's submitted correctly to the AjaxUpdater constructor (verified by alert just before the call). However, the strange thing is that the first call (after reloading the page, e.g.) works and expands the tree, and the second (and every after that) one is corrupted.

Sorry, could have thought of that in the first place... Tested it in several Browsers now:

Firefox 2.0.0.1: inserts the apache error page instead of the HTML expected (Request-URI Too Large - The requested URL's length exceeds the capacity limit for this server). That was the Browser this occured to me and on which my original post was based.

Opera 9.02: does remove the HTML it was supposed to replace (the node in the Tree disappears) plus some surrounding HTML it's in (e.g. the expand-'+' is gone afterwards although it's not in the updated container)

IE6: Nothing does happen, it just switches the expand icon's state without further changes.

I'd expect the different behaviour depends on how the browsers handle long URLs themselves resp. broken HTML (the Apache error page is a whole page in itself, so duplicate <html>-tags and the like are obviously not ok). In all 3 browsers the RC1 code works perfectly. Sidenote: i know some of the ids used are not valid, because they start with ':', but that should not be a problem, at least it hasn't been before with RC1, and the problem occurs on request, not response.

Function generating the URLs:

var sbMenu = {
	
	// open/close menu branches
	toggleMenuEntry : function (sNodeID) {
	
		var nodeIcon = $('icon' + sNodeID);
		
		if (nodeIcon.getAttribute('name') == 'close') {
			sbMenu._updateMenuEntry(sNodeID, 'close');
		} else {
			sbMenu._updateMenuEntry(sNodeID, 'open');
		}
		
	},
	
	// just reload a branch
	reloadMenuEntry : function (sNodeID) {
		sbMenu._updateMenuEntry(sNodeID, 'open');
	},
	
	// update a branch with desired method
	_updateMenuEntry : function (sNodeID, sMode) {
	
		var nodeItem = $('entry' + sNodeID);
		var nodeIcon = $('icon' + sNodeID);
		var nodeChildren = $('children' + sNodeID);
		
		var sNodePath = sNodeID;
		
		sNodePath = sNodePath.replace(/::/g, '!');
		sNodePath = sNodePath.replace(/:/g, '/');
		sNodePath = sNodePath.replace(/!/g, '::');
		
		switch (sMode) {
		
			case 'reload':
				alert('reload not finished yet');
				/*var sUrl = 'backend.view=menu&subjectnode=' + sNodePath;
				var sID = 'entry' + sNodeID;
				var myAjaxOpener = new Ajax.Updater( 
					sID,
					sUrl, 
					{
						method: 'get', 
						parameters: null 
					}
				);*/
				break;
				
			case 'close':
				nodeIcon.setAttribute('name', 'open');
				nodeIcon.setAttribute('src', 'modules/sb_system/themes/_admin/images_sysicons/tree_open.gif');
				
				if (nodeChildren != null) {
					nodeItem.removeChild(nodeChildren);
				}
				
				var sUrl = 'backend.view=menu&close=' + sNodePath //+ '&subjectnode=' + sNodePath;
				var myAjaxCloser = new Ajax.Request(
					sUrl, 
					{
						method: 'get', 
						parameters: null
					}
				);
				break;
				
			case 'open':
				nodeIcon.setAttribute('name', 'close');
				nodeIcon.setAttribute('src', 'modules/sb_system/themes/_admin/images_sysicons/tree_close.gif');
				
				var sUrl = 'backend.view=menu&open=' + sNodePath //+ '&subjectnode=' + sNodePath;
				//alert(sUrl);
				var sID = 'entry' + sNodeID;
				var myAjaxOpener = new Ajax.Updater( 
					sID,
					sUrl, 
					{
						method: 'get', 
						parameters: null 
					}
				);
				break;
		
		}
	
	}

}

HTML of the tree all collapsed (sorry, not prettyprinted, i'll manually beautify one entry):
