[Web Coding series]: A tutorial on .htaccess

I am hiring writers to complete my book titled 'Web Coding'. Your job is to complete a chapter on .htaccess .htaccess is a directory-level configuration file placed in the web server. The topics covered include all the 'tricks' that can be done with .htaccess. such as URL redirection and password protection. I can't get a book serious on this topic. However, the web serves as a good repository of such techniques. As such, your job is to dig out all techniques pertaining to .htaccess from the web, and compile them into a chapter. I expect about 15 different techniques to be noted, but more are welcomed. I expect flawless english. The format should resemble as much as possible the format of the existing chapters. All commands should be explained with examples of code snippets, as what has been done in the existing chapters. Tables and screenshots, where appropriate, should be added. Organised into sections, your tutorial should expect the reader to know nothing about .htaccess. Based on my rough estimation, the tutorial should span about 30 pages, but up to 50 pages is allowed. As you can see, the writing should be highly compact, succinct and concise, with absolutely no nonsense or trivial notes. You should post your partial writing to me periodically to ensure that you are on the right track of writing. If the book is to get published successfully, your name will be attached to your chapter. After the publication of the book, the writer of this chapter has no right to claim any royalty nor any monies relating to the sale of this book in future.
