support the more standard request.abort() instead of request.transport.abort()

[tschaub]

I'm calling this a bug because I don't want to be locked in to a weird API. The loadURL function is used a lot. More than other Ajax stuff. It should return something with the XMLHttpRequest interface. See the Request proposal? for my preference.

I'd like to get out from under this prototype.js mess instead of getting more deeply buried in it.

If nobody else has an opinion here, this shouldn't hold up the release.

We need to either do this in 2.6, or 3.0: It was added in 2.6, and I'm okay with breaking the API since it isn't in a release yet, but as soon as it is, it will make me cranky.

[crschmidt]

Also, I think you're right that it should be changed, since that likely wasn't clear from the above.

Like this?

Great solution. Needs a bit more work.

Tests passing (FF & Safari).

make loadURL look like it returns a real XHR instance

[crschmidt]

Tests pass. API Changing is an API that was added since 2.5. Seems relatively low risk. Please commit.

(In [6408]) The loadURL function now returns something that acts more like XMLHttpRequest should. If you name this return request, call request.abort to abort the request. r=crschmidt (closes #1386)
