Check the value of GATEWAY_INTERFACE inside %ENV, it should be CGI-Perl; if you need a little example, take a look at the code of CGI.pm and then,please, read the online manuals at mod_perl site, you will find everything you need and even more ;-) Ciao, Valerio	[reply]

The mod_perl guide has all of the answers. One way of doing it is to check for $ENV{MOD_PERL} - see Testing via a CGI script for more info.	[reply]

Another source of useful information - There is a perl-status switch, set this in httpd.conf, and you'll have access to lots of useful info about mod_perl and it's workings. -- Anthony Staines	[reply]

Or remotely... `telnet 127.0.0.1 80 HEAD / HTTP/1.1` [download] (you should substitute an the ip address of the machine in interest for 127.0.0.1 in this example) The should reply something like `HTTP/1.1 400 Bad Request Date: Tue, 17 Sep 2002 23:32:19 GMT Server: Apache/1.3.26 (Unix) Debian GNU/Linux mod_gzip/1.3.19.1a mod_p +erl/1.27 DAV/1.0.3 Connection: close Content-Type: text/html; charset=iso-8859-1 Connection to host lost.` [download] Note the presence of something like mod_perl/1.27 says that mod_perl v1.27 is running in Apache.

You can check the Apache `error_log`, look for the following line (versions of Apache/mod_perl will probably vary): `[Mon Sep 17 05:29:13 2002] [notice] Apache/1.3.26 (Unix) mod_perl/1.27 + configured -- resuming normal operations` [download] -- vek --	[reply] [d/l] [select]

Just like blm's method and PixelRat's one, this indicator is only helpful in finding out whether Apache has mod_perl support at all. It does nothing to verify whether a specific script is served by mod_perl or runs under mod_cgi. Makeshifts last the longest.	[reply]

use /apachedirectory/bin/httpd -l to see which your compiled-in modules are. don't forget to add an alias to you httpd.conf	[reply]
