SYMPTOMS
========

When you submit an HTML form or click a link to a script from the web browser,
you may receive an error similar to the following:

   CGI Error

   The specified CGI application misbehaved by not returning a complete
   set of HTTP headers. The headers it did return are:

   Can't open perl script "c:\inetsrv\wwwroot\scripts\test.pl":
   No such file or directory

CAUSE
=====

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.

MORE INFORMATION
================

The Common Gateway Interface (CGI) 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. The
only headers currently supported by the CGI specification are:

   Content-type:
   Location:
   STATUS

Additional information about these headers can be found in the HTTP Protocol and
CGI Protocol draft specifications available at http://www.w3.org.
