Chapter 12. Extra Modules

In addition to the standard modules mentioned in Chapter 1, which we suggest you compile into your copy of Apache, there are a number of more volatile modules available. We do not propose to document them in this edition of the book, but the list might be interesting. Be warned: modules designed for earlier versions of Apache may need updating before they work correctly with Version 1.3. Modules can be found in several places:

• The Apache ../src/modules directory. This contains the standard modules plus (in the 1.3 release) subdirectories experimental and extra. The curious may find a search rewarding. At the time of writing there was only mod_mmap_static, which allows faster serving of slowly changing files.

• The Apache FTP directory at ftp://ftp.apache.org/apache/dist/contrib/modules/. At the time of writing the list was as follows:
