I want to display the 404.html page for routes that are not defined in  
my application. So if a visitor tries to visit  
“http:://www.yoursite.com/undefined” instead of “Routing error” they  
will get my 404.html page.

How can this be handled? Is there a way to setup something in routes.rb  
for all routes not defined and/or not controller/action? Thanks…

Not sure if this is the best way to go about this, so hopefully  
someone else will comment, but if you put:

map.connect ‘\*anything’, :controller =\> “blah”, :action =\>  
“unknown\_request”

at the end of your routes, it will map anything it doesnt recognize  
to the “unknown\_request” action.

Hi  
I think you place your application in production environment.  
when routes is not match then it gives 404.html page. so visitor get  
your default error message instead of routing error.
