New Post: how spservices work - quick question please

Hi All,
     Just got a quick question here.
I have been using spservices for a while now and i love it because it just works.
But lately i'm working on a project with a client and i need to use spservices for this project.
The intranet site is like an extranet but not sharepoint online i reckon service provider is hosting it for the client publicly but it seems they aren't mapping the url correctly as it a https:// site.
I don't have direct access to the server and no luck using sharepoint designer either.
So i decided to use Content Editor webpart with SPServices.
The first thing was to test if i can get the current site but no luck using

<scripttype="text/javascript"src="/Style%20Library/Scripts/jquery.min.js"></script><scripttype="text/javascript"src="/Style%20Library/Scripts/jquery.SPServices-0.7.2.min.js"></script><scripttype="text/javascript"language="javascript">
$(document).ready(function() {var thisSite = $().SPServices.SPGetCurrentSite();
         alert(thisSite);
});</script>

when i look at firebug it says :

Exception of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown
The Web application at XXXX could not be found

when i look at the web services WDSL

https://xxx/_vti_bin/Webs.asmx?WSDL

and look at the address location its another URL e,g http://xxx.local/_vti_bin/Webs.asmx

Am i thinking correctly and if yes what do i need to to tell them to change.

Cheers
