How to send data to remote server using Javascript

Question

I need to send data to a remote server using javascript. How do I do this?

Background info: There\'s a webpage from which I extract some information

Answer 1

• submit a form using POST. That is working on all browsers cross domains. Have the server process the post. the form can be submitted to a hidden frame if you want to simulate AJAX
• Use Cross Domain Resource Sharing (MDC) (IE XDR)

• use a web bug (create an image, set the source to the url you want - smallish GET requests only)

  var img = new Image();
img.src="http://www.otherserver.com/getxml?xml="+encodeURIComponent(yourXML); (Oops, I see Lebedev did more or less the same in his update)

• use a proxy, i.e. have your server talk to the other server for you
