Hi, I looking to learn the language for a htaccess, is this written in C++? I know how to write a simple 301 redirect but I would like to understand how the language is actually written, what all the characters, numbers and symbols actually mean and how to fit them together, I hope this makes sense! On another note, similar question, I have used a gbase.php file for google shopping feed, same question again, what could I learn to understand how it all fits together! Any decent books or pointers are much appreciated! Thanks again. John
