Rack middleware which will perform a find/replace on the response body. This is basically a re-implementation of the following Rails code:
after_filter {|c| c.response.body.gsub 'foo', 'bar'}
The advantage of this module over the above code is:
-
It will work in any rack-compatible environment.
-
It is streaming friendly as it operates on each chunk given to rack.
use Rack::Replace, 'foo', 'bar' use Rack::Replace 'HOST' {|env, match| env['HTTP_HOST']}
For more advanced uses see rack_image_size and rack_new_window.
