Is rack-offlline supports Rails 2.3.5?

Rails

Hi,

I am going to add offline feature in our web application. But, that
application was developed using Rails 2.3.5. I planned to use
rack-offline gem.

While using that gem, we have to add a statement like below in
“routes.rb” file (to generate “cache-manifest” file):

match “/application.manifest” => Rails::Offline
But, that statement is like “Rails 3” route statement but not “Rails 2”.

Is “rack-offline” supports Rails 2.3.5?

Thanks,
Kumar
