A long-awaited and much appreciated suite of Apache 2.0 modules, which I use simply to access POSTed data from mod_perl, but which does much more, including giving access to Cookies, file uploads, errors, hooks, and more.
With this fast and stable suite, CGI.pm in mod_perl is finally unncessary.
This review once made sad comments on the inability of this module to install via CPAN. However, the fault has been rectified, and a vast library of documentation has been added. Excellent work: 5/5.
