For the above example, this would mean to include all values that are bigger (>, not >=) than 0 and smaller than 10. ...

I've built out a fairly complex Rails (2.3.8) app with a lot of jQuery ajax requests. There is an occasional bug, which I have difficultly replicating, where a jQuery $.ajax({..}) request will request a page it shouldn't (like the dash page, which is never called with an ajax request)... What ensures is absolutely madness. Incredibly st...
