The requests are displayed in the firebug console for example.
Ah, I thought you meant the server console window. I should probably
have realised, as you said it was angular code.
How to stop stuff displaying in the FF console is not a Rails issue, I
don't think. I doubt if it is possible.
Even if there were a way anyone can inspect the javascript code and
work out what it is doing, if they are really interested.
