mod_rewrite And Friends
Book: The definitive guide to mod_rewrite, URL manipulation, and content munging with the Apache http server
I started writing this in LaTeX, but those .tex files will go away soon, as I convert them to rst. See http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html for more about reStructuredText.
'make latexpdf' to build PDF version. Various other make targets build other formats. You'll need to have various TeX things installed, like texlive, texlive-collection-extras, texlive-chextras, texlive-bold-extra and texlive-collection-latexextra. And you'll need to install Sphinx - http://sphinx-doc.org/
I'll document all the dependencies as soon as I figure them out. Let me know if stuff doesn't build.
