For any url that looks like "/blah" the variable "params[:something]" 
will be set to whatever comes after the "/"

For example (using curl):

$ curl localhost:5000/blah
Print blah!
$ curl localhost:5000/whatever
Print whatever!
$ curl localhost:5000/something
Print something!
$ curl localhost:5000/whee
Print whee!

The ":something" in your route just determines the name of the parameter.
