[Ruby] Browser Back Problem with Rails

[Neil Moomey]

I fixed my browser back problem.  Thanks Mike for pointing me in the
right direction. First I added the following to each page:

expires_in 1.hours, :public => true, :private => false

Then I concluded that Session data can't handle this very well.  The
page would display the same data for the first couple back clicks and
then it would finally display the first page results.  So I rewrote my
app using Hidden Fields to pass data instead of session and everything
works fine.  I can click Next as many times as I wish and click the
back arrow and it will display the cached pages.  Sometimes doing
things the old fashion way is best.
