We have used mod_perl 1.26 and Apache 1.3.24 in most of the examples in this book. You should be able to reproduce all the presented examples with these or later versions of mod_perl and Apache.
We have tested all the examples with Perl 5.6.1. However, most of the examples should work the same under all Perl versions between 5.005_03 and 5.8.0.
At the time of this writing, Apache 2.0 is very young and mod_perl 2.0 is still in development. See Part V for information on mod_perl 2.0. While much of this book should apply to both mod_perl 1.x and mod_perl 2.0, the code has been tested only on mod_perl 1.26.
