Here is my sandbox https://github.com/pavelsr/mod_perl_sandbox
When I make docker-compose up then go to http://localhost:3000/env.pl resulted html is downloaded, not served.
Under CGI mode (with removed -DMODPERL in docker-compose) everything works fine.
Seems like ModPerl::Registry does not process Content-type: text/html
What I need to do fix in httpd.conf ?
Adding PerlOptions +ParseHeaders wil not fix the problem
