Finding the Contextpath from XMLHTTP Request

[jad2006]

Hi
We tried creating AJAX based test kit, It will prompt for a URL to be tested. It will analyse all the links in the URL and trigger ajax calls to each and every link in the page and it will check the status of the links and update the same. This worked fine with absolute urls, but if there are relative urls in the page its not able to properly construct the url since it does not know the context path
Is there any way by which we could find out the ContextPath of the XmlHTTPRequest

This may be useful to resolve relative paths to absolute paths, in the context of the current location.

[CODE=javascript]pathTrack= function(url){
if(url.indexOf( location.protoc ol)== 0 || /^(mailto|http)\ :/i.test(url)) return url;

url= url.replace(/\\/g,'/');
var Loc= location.href.r eplace(/\\/g,'/');
var ax= Loc.indexOf(loc ation.pathname) ;
while(Loc.charA t(ax)== '/')++ax;
var Rte= Loc.substring(0 ,ax);

if(/^\//.test(url)) return Rte + url;

Loc= Loc.substring(0 ,Loc.lastIndexO f('/'));
if(/^[^\.]/.test(url)) return Loc+'/'+url;

var L= ax;
while (url.indexOf('. ./')==0 ){
ax= Loc.lastIndexOf ('/');
Loc= Loc.substring(0 ,ax);
url= url.substring(3 );

if(ax< L) throw new Error('Bad path-'+Loc+'/'+url);
}
return Loc + '/' + url;
}[/CODE]

here is a simple, rock solid way to qualify paths;

function qualifyPath(paf) {
    var i = new Image();
    i.src = paf;
    return i.src;
}

//example:

alert (qualifyPath("localPage.htm"))
alert (qualifyPath("../parentPage.htm"))
