[Ruby] Browser Back Problem with Rails

[Michael Judge]

Hey Neil,

I'm pretty sure it's your page's response headers.  From p.425 (Agile  
Web Development with Rails -- 2nd Edition), where it's talking about  
the controller environment, it says:

"headers - A hash of HTTP headers that will be used in the response.  
By default, Cache-Control is set to no-cache..."

Aha!  So the answer is to set headers["Cache-Control"] to a  
reasonable value in your controller, and Internet Explorer will think  
it's a static page.  I don't know what a reasonable value would be,  
but this should be enough info to get you pointed in the right  
direction.
