" WWW_SERVER_SOFTWARE == "HTTPd-WASD/11.3.0 OpenVMS/AXP" WWW_UNIQUE_ID == "aLAVVwAAAAQAABhrKEk" 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!
