</div>

I want to present different view depending on the url.  
example below:

[http://myapp/start/show?url=xZq](http://myapp/start/show?url=xZq)  
[http://myapp/xZq](http://myapp/xZq)

both addresses are controlled by a single controller and the same  
action.  
the second url is only mapped in routes.rb

how can I distinguished the mapped url and present a slightly different  
view  
in it?

in your mapping you can pass a parameter that will indicate this is a  
mapped  
link…

I want the mapped url to be as short as possible, so passing a parameter  
in  
the url itself is out of the question.  
unless there’s some other way I’m not aware of.

thanks for reply.

I was meaning something like this

map.connect ‘:link’, :controller =\> ‘start’, :action =\> ‘show’, :url  
=\> :link, :mapped =\> ‘1’

I assume :mapped will be stored in the @params?
