ASF chairman Greg Stein sparked off a long
debate this week on the development list by drawing attention to
an article on Apache 2.0
adoption published last month. The discussion centred around
using PHP with Apache 2.0, and the two main problems with doing
so: thread-safety issues with the myriad third-party libraries
which PHP uses, and the compatibility of the PHP engine API with
the Apache 2.0 filters interface. It was accepted that the former
problem will take some time to disappear: in the mean time, using
PHP with the non-threaded "prefork" MPM under Apache 2.0 is the
only recommended combination. Several ideas for fixing the API
compatibility problems were exchanged.
As a demonstration of Apache 2.0's support for protocols other
than HTTP, Ryan Bloom wrote a
mod_pop3 module supporting the mail protocol POP3.
The module has remained largely untouched since its inception in
August 2001; a proposal to move it into the httpd-2.0
CVS repository has received several positive votes.
In this section we highlight some of the articles on the web
that are of interest to Apache users.
"JSP Quick-Start Guide for Windows"
walks you through the steps of setting up a JSP-enabled Web server on
a Windows PC using Tomcat 4.1.18 and Apache 2.0.44. It also shows
you how to integrate Apache and Tomcat by using
mod_jk as other connector modules such as
mod_webapp does not work reliably on Windows
and mod_jk2 does not have comprehensive
documentation on how to configure it. It ends with an example of a
working JSP in Apache.
In the November 2002 issue of Linux Magazine, the article entitled
lists the PHP code for implementing a simple Web interface to
query and display useful information from all Apache traffic that has
been stored in a MySQL database. This example just provides a list
of domains, the total number of requests for each domain, the most
recently requested URI of a domain, the most popular URI of a
domain, and how many hits for each URI but you can customise the
example scripts to output other statistics.
"Creating Your Own CA"
talks about Certificate Authorities (CA) and explains how you
can act as your own CA by creating your own CA certificate and
then signing certificate requests with your CA's key. All these are
done with the CA.pl utility, part of the OpenSSL toolkit.
