(Other stories by Ryan Bloom)
"This month, I will continue to explore filtered I/O by writing a simple filter to add a header and/or footer to every page that the server sends. This filter will not explore all of the power of the filtered design in 2.0, but it is a good start."
"Rather than just review the filtering code, I am going to go over the entire module, so that we can all see how everything fits together. The idea behind this filter is that many sites want to add a small piece of text to the top or bottom of every page that is served. With Apache 1.3, this is very difficult to do, but with filtering this becomes very simple. This module will actually offer two methods for adding text to the top and bottom of each page. The first option is to use a file from the disk, and the second is to specify a text string that will be inserted directly into the page."
