		<description><![CDATA[While doing a bit of research tonight I came across a reference to mod_substitute. This nifty module allows you to substitute text in the HTTP request body, which provides an easy way to do things similar to the following: &#60;Location /private&#62; AddOutputFilterByType SUBSTITUTE text/html Substitute s/SECRET/XXXXX/ni &#60;/Location&#62; I digs me some Apache!]]></description>

		<description><![CDATA[Building and maintaining Apache chroot environments can be a royal pain. Creating a chroot environment for Apache requires you to first identify all the libraries and applications that are required to run the httpd processes. Once you identify the dependencies, you need to create a chroot environment that contains these files. After you successfully create [...]]]></description>

		<description><![CDATA[A few weeks back I helped a friend build PHP on a server with a non-standard directory structure. Changing the structure to use common defaults wasn&#8217;t an option, so we needed to adjust the PHP configure script to point to the pertinent places. Here is what we came up with: $ export CPPFLAGS=&#8221;-I/home/apps/include -I/home/apps/include/mysql&#8221; $ [...]]]></description>

Each container is required to have a ServerName directive, which contains the domain name associated with the virtual host. In addition to a server name, one ore more aliases can be associated with the virtual host with the ServerAlias directive. Aliases can contain a domain, [...]]]></description>

		<description><![CDATA[I support a fair number of Apache web server instances, and periodically need to measure the time it takes Apache (and it&#8217;s various modules) to process a request. On Solaris 10 hosts, I can use DTrace to retrieve this information on the fly. Since Solaris 9 and CentOS and Redhat Linux don&#8217;t come with DTrace, [...]]]></description>

		<description><![CDATA[On busy web servers, the process of writing to the access_log can sometimes overwhelm the spindles in a server. In Apache 2.0.41, the developers added the experimental &#8220;BufferedLogs&#8221; directive to buffer access_log entries in memory, and write them out as a single group. The documentation indicates that setting &#8220;BufferedLogs&#8221; to &#8220;On&#8221; enables buffered logging, but [...]]]></description>

There are numerous ways to do this, and I covered several client centric solutions in my SysAdmin article Debugging Web Applications.
