Powered by mod_perl
Here's a quick and easy way for you to advertise your use of mod_perl.
Add this to your Apache conf.
Header add X-Powered-By mod_perl/2.0
You should be able to add it to any appropriate section or directive. I added it right below "ServerTokens Prod".
I blog about Perl.
I wonder who will be detecting this header? Btw, I recently had to turn off X-Powered-By: PHP on my Debian servers because some vulnerability scanner picks the PHP upstream version from this header and (unaware about Debian patch version) insists that the servers are vulnerable due to PHP version being smaller than the rexommended one.
In general, it's not a great idea volunteering too much extra information to potentially misbehaved folks. At a minimum, the following two directives should be present in the
apache2.conffile:ServerSignature Off
ServerTokens Prod

Perhaps web developers who want to know what technology is being used to run your awesome web app would look.

I agree. But ServerSignature Off / ServerTokens Prod still shows "Apache". So I don't think it's that big of a deal to show "mod_perl"
Leaving out "/2.0" seems wise (although it doesn't indicate the actual version.)
FWIW, I pulled the config line out of an old document created by the mod_perl developers in a discussion about promoting mod_perl.
