request.raw_post

Hi, this is the last post on this AJAX example  http://www.railshosting.org/#live_searching  - thanks rails gurus.

What exactly does the request.raw_post value give you?  I can't seem to find any documentation on it (probably looking in the wrong place).  The docs and wikis I've seen seem to imply that you would say something like

with => 'myVal=' + encodeURI .........

and then access params[:myVal] in the controller.  What does the raw_post value contain?  Does it just default to the value of the control your observing?  Any disadvantages to using it?

Thanks!

If you want to see the value of something, just raise it:
raise request.raw_post.inspect

Or, log it:
logger.debug request.raw_post

That said, the Rails documentation link for raw_post is here:
http://api.rubyonrails.com/classes/ActionController/AbstractRequest.html#M000818

I normally do the :with because I like to name the parameter, so I'm not exactly sure what raw_post contains.
