A reviravolta do desenvolvimento web
This document discusses the evolution of web development in Perl, from CGI scripts to modern PSGI-based frameworks. It introduces PSGI as an interface between web applications and web servers, and Plack as a toolkit for building PSGI applications and middleware. The document outlines many PSGI web servers and frameworks that can be used to build and deploy Perl web applications according to the PSGI standard.
