Instance Method Details

#merge_script_names(previous_script_name, new_script_name) ⇒ Object

Keeps the part of the script name provided by the global context via ENV, which ‘mount` doesn’t know about since it depends on the specific request, but use our script name resolver for the mount point dependent part.
