Instance Method Details



  

    #merge_script_names(previous_script_name, new_script_name)   (private)
  



  

    

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.
