Apache phrasebook

Because Apache is the most-used web server running today, many Apache administrators are novices or don't complete the same tasks on a weekly basis. These readers are hungry for a concise, easy-to-use reference that puts essential code "phrases" at their fingertips. While there are many Apache books on the market, none of them answer essential questions quickly and efficiently. Administrators may want to fix a small problem that doesn't require pages of confusing explanation. Today's problem will likely not be tomorrow's problem, and the non-guru administrator wants answers each day to keep his server up-and-running. Apache Phrasebook is the guide to Apache that people will seek first to get the job done. Skipping the usual tutorial on Apache, the Apache Phrasebook goes straight to practical Apache tools, providing immediately applicable solutions for frequent tasks and code so flexible that it is easily adapted to the administrator's needs.
