Create loading message

How to create a loading message or spinning wheel for each page .

I think it has to be put on interceptor but where ?

thank you

I'd do it in the layout for your views. Use onLoad and jQuery (or
mootools, mochikit, etc) to do the loader message and voila, should be
good to go. No reason that I can think of to use an interceptor but
there may be a use case I'm not seeing at the moment.

can you show some examples

Thank you

Google "blockUI".. I use that plugin.
