javascript: cancel all kinds of requests

Question

My website makes a lot of requests. I often need to cancel all current requests, so that the browser is not blocking relevant new requests.

I have 3 kinds of requests:

• Ajax
• inserted script-tags (which do JSONP-Communication)
• inserted image-tags (which cause the browser to request data from various servers)

For Ajax its no problem as the XMLHttpRequest object supports canceling. What I need is a way to make any browser stop loading resources, from DOM-Objects.

Looks like simply removing an object (eg. an image-tag) from the DOM only helps avoiding an request, if the request is not already running.

UPDATE: a way to cancel all requests, which are irrelevant, instead of really any request would be perfect.

Answer 1

I think document.close() stops all requests, but I'm not so sure about it.

Answer 2

window.stop() should cancel any pending image or script requests.
