For some reason, we left out Python--a perfectly good language, with some useful features of its own--so here is what we should have said in the book. Python is freeware and you can download it from www.python.org .

And, although we all know very well just how to do it in our heads, 99 times out of 100, we start out with an existing file and modify it. I thought it might be interesting to run through such a file, to look at how it works and see where the subtle jokes are.

This time, I am going to cover one of the least-discussed features in Apache 2.0. One of the biggest advantages of Apache over other web servers is how easy it is to write powerful modules. Apache has used modules since version 1.0 to implement everything but serving basic, static files. Because Apache itself used modules for... http://www.oreillynet.com/pub/a/apache/2001/09/13/apache_2.html 09/13/2001 In the last article , we discussed the basics of Apache 2.0 filters and there was enough information to get started, but not enough to write a functioning filter. In this article, we will finish discussing output filters. After reading this article, you should be able to write your own Apache filters. When the filter interface was first designed, it was written for the Apache developers and very little attention was paid to making it easy for other people to write their own... http://www.oreillynet.com/pub/a/mac/2002/03/08/apache_mac_5.html by Kevin Hemenway 03/08/2002 Editor's Note: Kevin returns with his fifth article concerning Apache, OS X, and the immense power available to the common man. Having established a good, firm pool of Apache knowledge in the first four articles , Kevin takes the time to focus on a popular supplementary technology, namely the database server MySQL. Even after getting that prime parking spot, and even after getting one of those deficit-inducing, dotcom-deflating chairs, you stare down at the... http://www.oreillynet.com/pub/a/apache/2001/08/23/apache_2.html 08/23/2001 When the Apache developers first began talking about Apache 2.0, one of the major goals was for one module to be able to modify the output of another. This goal was realized earlier this year with the sixth alpha version. The mechanism used to make modifications are called filters. Originally it was difficult to write filters, but during the past few releases, the developers have improved the interface so that filters are much easier to create. This article will cover some of... http://www.oreillynet.com/pub/a/mac/2003/04/04/apache_jaguar_pt1.html by Kevin Hemenway coauthor of Mac OS X Hacks 04/04/2003 Editor's note: Most people know that Mac OS X ships with a built-in Apache web server, but don't realize that it's easy to configure and run. In fact, you can host a web site in minutes, after completing just a few simple steps. But that doesn't mean that Mac OS X is a lightweight in this category. It's not.

They will not bother to check out the Apache manual either. Custom error messages are not something to (just) show off with. In terms of (web-)usability, you are able to display a more friendlier or meaningful message to your users, and everyone will live happier ever after.

In this article, we'll focus on input filters. The two filter types are very similar and many of the concepts that we have already covered with output filters can be successfully applied to input filters. However, input filters differ from output filters enough that it is important to dedicate an article to them. The first difference between input and output filters is that there are two different... http://www.oreillynet.com/pub/a/apache/2003/01/02/apache.html by Peter Laurie , coauthor of Apache: The Definitive Guide, 3rd Edition 01/02/2003 Every couple of years the job comes round of revising Apache: The Definitive Guide to produce a new edition; this past year it was time for number three.

You can serve an alternate page based on the name of the page that was not found, create a page on the fly from a database, or send an email about the missing page to a webmaster.
