title: mod_rewrite not behaving nicely
body: <p>I have a simple project in which I'm attempting to do some rewriting of URLs to point to a couple PHP scripts.</p>
  <p>My current path on the server is /project/engine, and I've dropped an .htaccess file in that directory to perform my rewriting:</p>
  <pre><code>RewriteEngine On
  RewriteRule ^(get|post)/(\w+)$ $1.$2.php
  </code></pre>
  <p>It's a pretty simple rewrite. I'm basically looking to rewrite a URL like this: <code>/project/engine/get/class</code> to this: <code>/project/engine/get.class.php</code>.</p>
  <p>Can anyone spot the error here? If I try accessing the URL in a web browser, I get a 404 and the following error in Apache error log:</p>
  <pre><code>[Wed Dec 29 14:57:17 2010] [error] [client 127.0.0.1] Negotiation: discovered file(s) matching request: /var/www/project/engine/get (None could be negotiated).
  </code></pre>
  <p>My apache configuration file looks like the following:</p>
  <pre><code>&lt;VirtualHost *:80&gt;

  <p>Also, here is my apache2.conf file:</p>
  <pre><code>#
  # Based upon the NCSA server configuration files originally by Rob McCool.
  #
  # This is the main Apache server configuration file.  It contains the
  # configuration directives that give the server its instructions.
  # See http://httpd.apache.org/docs/2.2/ for detailed information about
  # the directives.
  #
  # Do NOT simply read the instructions in here without understanding
  # what they do.  They're here only as hints or reminders.  If you are unsure
  # consult the online docs. You have been warned.  
  #
  # The configuration directives are grouped into three basic sections:
  #  1. Directives that control the operation of the Apache server process as a
  #     whole (the 'global environment').
  #  2. Directives that define the parameters of the 'main' or 'default' server,
  #     which responds to requests that aren't handled by a virtual host.
  #     These directives also provide default values for the settings
  #     of all virtual hosts.
  #  3. Settings for virtual hosts, which allow Web requests to be sent to
  #     different IP addresses or hostnames and have them handled by the
  #     same Apache server process.
  #
  # Configuration and logfile names: If the filenames you specify for many
  # of the server's control files begin with &quot;/&quot; (or &quot;drive:/&quot; for Win32), the
  # server will use that explicit path.  If the filenames do *not* begin
  # with &quot;/&quot;, the value of ServerRoot is prepended -- so &quot;/var/log/apache2/foo.log&quot;
  # with ServerRoot set to &quot;&quot; will be interpreted by the
  # server as &quot;//var/log/apache2/foo.log&quot;.
  #
  
  ### Section 1: Global Environment
  #
  # The directives in this section affect the overall operation of Apache,
  # such as the number of concurrent requests it can handle or where it
  # can find its configuration files.
  #
  
  #
  # ServerRoot: The top of the directory tree under which the server's
  # configuration, error, and log files are kept.
  #
  # NOTE!  If you intend to place this on an NFS (or otherwise network)
  # mounted filesystem then please read the LockFile documentation (available
  # at &lt;URL:http://httpd.apache.org/docs-2.1/mod/mpm_common.html#lockfile&gt;);
  # you will save yourself a lot of trouble.
  #
  # Do NOT add a slash at the end of the directory path.
  #
  ServerRoot &quot;/etc/apache2&quot;
  
  #
  # The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
  #
  #&lt;IfModule !mpm_winnt.c&gt;
  #&lt;IfModule !mpm_netware.c&gt;
  LockFile /var/lock/apache2/accept.lock
  #&lt;/IfModule&gt;
  #&lt;/IfModule&gt;
  
  #
  # PidFile: The file in which the server should record its process
  # identification number when it starts.
  # This needs to be set in /etc/apache2/envvars
  #
  PidFile ${APACHE_PID_FILE}
  
  #
  # Timeout: The number of seconds before receives and sends time out.
  #
  Timeout 300
  
  #
  # KeepAlive: Whether or not to allow persistent connections (more than
  # one request per connection). Set to &quot;Off&quot; to deactivate.
  #
  KeepAlive On
  
  #
  # MaxKeepAliveRequests: The maximum number of requests to allow
  # during a persistent connection. Set to 0 to allow an unlimited amount.
  # We recommend you leave this number high, for maximum performance.

  MaxKeepAliveRequests 100
  
  #
  # KeepAliveTimeout: Number of seconds to wait for the next request from the
  # same client on the same connection.
