[Fri Mar 02 17:02:29 2012] [error] [client ::1] malformed header from script. Bad header=this is a test : test.pl

tried my install "mod_perl" package but the same issue persists.

Code:

[root@server1~]# yum install mod_perl* -y

Please help..!!

First, send content type as "text/html" from perl script:

Code:

#!/usr/bin/perl
print "Content-type: text/html\n\n"; 
print "This is a test \n";

Make sure test.pl has executable permissions:

Code:

chmod +x /var/www/cgi-bin/test.pl
