A controversial patch was submitted this week, to allow the
DocumentRoot directive to be used within a
<Location> block. Part of the motivation
for this change was to allow the DocumentRoot to be "unset" for a
particular location, to prevent any files being served from the
filesystem within this portion of the URL space. It was revealed that
a new hook available in 2.0 already allows module authors to implement
this behaviour, and some
list members felt that this patch was unnecessary.
A new directive LogExcludeByType was added
to the 2.0 tree; this directive would disable logging of requests for
files which matched certain MIME types. This was added to overcome performance
problems with using the
methods of performing conditional logging, using
SetEnvIf and CustomLog.
After several comments that the directive was too specific, the commit
was reverted pending broader consensus.
Debugging continued of the problem with high load averages
generated by 2.0 on the live server running at apache.org. Despite a
great deal of analysis the developers seem no closer to finding the
Russell Pavlicek at InfoWorld gives his predictions for
future of open source in 2002. Amongst great things happening to
Linux, Russell predicts that Apache will finally be recognised as the
de facto standard in web servers.
"The shortcomings of Microsoft's IIS
will help spur Apache's rise, which should also be bolstered by Gartner's
recent recommendation to abandon the use of IIS as a corporate Web server."
In this section we highlight some of the articles on the web that are of
interest to Apache users.
of the series on Apache web serving with Mac OS X, Kevin Hemenway
shows you how to enable PHP support, test that it is working, retrieve
useful information from the error log, and use the
Order, Deny, and
Allow directives to restrict access to your
intranet. For the ambitious who wish to implement a
web-based POP email client using PHP, he recommends PHPost.
Due to the overwhelming responses from Mac OS X users, we heard
from the man himself that he plans to add two new articles to
the original three in this series. Isn't this good news?
As high-availability is critical for centralised authentication
and password services,
"Non-stop authentication with Linux clusters"
guides you in creating a reliable, highly available authentication server
using the OpenLDAP and Heartbeat packages on a pair of Linux
servers. It explains the basic concepts of LDAP and Heartbeat, and
then proceeds to give a detailed description on configuring and testing
An example of how to configure the Apache Web server with
mod_auth_ldap to authenticate users against the
LDAP server is included at the end of this article.
RMI (Remote Method Invocation) allows the methods of remote Java
objects to be invoked from other Java virtual machines. If an RMI client
is blocked by a firewall, one solution is to use HTTP tunneling to reach
the RMI server.
"10 Steps to RMI Tunnelling"
by David M. Howard is a step-by-step tutorial on how to implement
Sun's RMI servlet handler in Apache+Tomcat so that the web server
will forward RMI requests to the local RMI server correctly.
