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](“SCRIPT_NAME”), 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.
