FAQ Topic - How do I run a server side script?
-----------------------------------------------------------------------

You trigger a server-side script by sending an HTTP request.
This can be achieved by setting the ` src ` of an ` img `,
` Image `, ` frame `, or ` iframe `, or by using XHR, where supported.

An image will also
"swallow" the data sent back by the server, so that they will
not be visible anywhere.

var dummyImage = new Image();
dummyImage.src = "scriptURL.asp?param=" + varName;

Mozilla, Opera 7.6+, Safari 1.2+, and Windows IE 7
provide the ` XMLHttpRequest ` object
(Windows IE versions 5+, provides ActiveX to acheive an analagous
effect). ` XMLHttpRequest ` can send HTTP requests to
the server, and provides access the ` responseText ` or ` responseXML `
(when the response is XML), and HTTP header information.
