Ajax call from asp.net

Hi

Could anyone help me with a way to call the Ajax script below from ASP.net, preferably in VB.

$.ajax({type: 'POST', url: 'http://www.executiveplacements.com/Job_Post_Xml.asp', data: { XmlPacket: yourXmlVariable}, success:function(data){ /*process results XML*/; }, error:function(){ alert('Error processing data. Please try again.); } });

Thanks
