John,
Asking the obvious, if you don't want the code to run, why not remove
it or comment it out? I'm not entirely sure what you are after, so a
general response which I hope may still be useful.
Firstly, the protected code block has the structure:
begin
expr..
[rescue [error_type,..]
expr..]..
[else
expr..]
[ensure
expr..]
end
In this, the "end" statement ends the block. It does not stop the
program running. In this case, the end statement after your puts
'please login..' line closes the begin block.
To stop the program / script running, call the 'exit' method.
Alternatively, if you want to build in behaviour around the lack of a
browser, you could always use an if-block:
if browser
# do stuff when you have a browser
else
# do stuff when you have no browser (browser = nil)
end
