pls help.

The virtual domain has a virthost section in httpd.conf as follows:
<VirtualHost www.mydom.org>
   ServerAdmin webmaster@mydom.org
   DocumentRoot /home/www/mydom
   ServerName www.mydom.org
   <Directory />
    AllowOverride All
    Options FollowSymlinks Multiviews
    Order allow,deny
    Allow from all
   </Directory>
   ScriptAlias /cgi-bin/  /home/www/mydom/cgi-bin/
   <Directory /home/www/mydom/cgi-bin>
    AllowOverride All
    Options ExecCGI Includes
    Order allow,deny
    Allow from all
   </Directory>
   ErrorLog logs/mydom-error.log
   CustomLog logs/mydom-access.log common
</VirtualHost>


Yet, when I place a simple script such as
#!/usr/bin/perl
print "test";

Then I get internal server errors

I have tested it with all kinds of permissions; 755 and 777, but I still can't get it to execute.

Pls help.

Thanks

psimation,

You need to have you cgi scripts to send a proper http header.

Please could try the following;

#!/usr/bin/perl
print "Content-type:text/html\n\n";
print "<html>\n";
print "<head>\n";
print "<title>My Title</title>\n
print "<body>\n";
print "test";
print "</body>\n";
print "</html>\n";


----
The most important part is
print "Content-type:text/html\n\n";

This is to tell the browser that the subsequent data will by of text/html type.

Please visit http://httpd.apache.org/docs/howto/cgi.html for much detail informatio on how to get CGI to work with Apache.

Hope the information is useful.

cheers.

Thanks, but it still does the same:
Malformed headers ...
script executes fine from command line though...

Psimation.

Could you try replacing the config for vhost with this one;
ScriptAlias /cgi-bin/  /home/www/mydom/cgi-bin/

<Directory /home/www/mydom/cgi-bin>
   AllowOverride None
   Options None
   Order allow,deny
   Allow from all
</Directory>

Also look at Apache FAQ:
http://httpd.apache.org/docs/misc/FAQ.html#premature-script-headers
Also check the logfile (error_log) for any hints.

Psimation,

hey. did you copy-paste my code.  Watch there is a missing quote (");  This one might work.  And try to flush all the buffer by $|=1;

#!/usr/bin/perl

$|=1;

print "Content-type:text/html\n\n";
print "<html>\n";
print "<head>\n";
print "<title>My Title</title>\n";
print "<body>\n";
print "test";
print "</body>\n";
print "</html>\n";

cheers.

psimation,

If you are looking into developing CGI using perl, take a look at CGI.pm module (try "perldoc CGI" for some information).  It is actually a collection of modules for CGI manipulation.  Quite neat.

there is some examples too.

cheers.
