The specified CGI application misbehaved by not returning a complete set of HTTP headers. This error is caused by missing or malformed CGI header information. In this case the headers are missing because the script file could not be run, resulting in that error message being displayed instead of the output from the script.
Specification calls for the script file to return at least one header.
These headers fill out the remainder of the HTTP headers as required by the HTTP protocol. The HTTP protocol also requires a blank line between the end of the headers and the start of the document.
