Map path "" (empty path, will be an error) to a file specification.

  This will be done using a callout of "MAP-PATH: "

  The server responded with: "400 Bad parameter"

  400 is a error code, hence the error message is "Bad parameter"


As an error occured in the first callout, the second, to map it back to a
path, will not be done.  Append a path to the script URL and see what happens!
