title: Writing a mod security rule to block access to a PHP file
body: <p>I wish to block access to any file with name "modules.php" in any website.
  I have written a Rule in mod security but I'm not sure if it is working or not?
  here is the rule</p>
  
  <pre><code>SecRule REQUEST_LINE "@rx modules.php" \
  "phase:2,block,severity:2,msg:'Blocking access to modules.php files.'"
  </code></pre>
  
  <p>Is that correct?</p>
