[expert] cgi scripts

[Seb]

Hi all!

    I'm running a Mandrake 6.0 server with Apache 1.3.6 and i made a c
program which return an html document on stdout named test.cgi an d located
in /home/httpd/html/seb/c . When apache try to read it he return me an
Internal Server Error and in the log file it is malformed header for script.
Bad header=<DOCTYPE.....

What's that ?
