title: 403 forbidden error and html meta tags
body: <p>I am using php/mysql with apache 2 server.</p>
  
  <p>I have a php data entry form which use a <code>&lt;textarea&gt;</code> html tag.</p>
  
  <p>I usually enter some meta tags like 'description' or 'keywords' and when i save the form, the textarea save in a mysql textarea fieald at my database.</p>
  
  <p>There was no problem for a long days, but a few days ago when i try to save data entry form, it generates 403 forbidden error.</p>
  
  <p>There is something strange on it. If i enter only one meta tag like
  <code>&lt;meta name="description"...&gt;</code> in textarea, there is no problem, but if i press the 'Enter' key and  add the 2nd tag like <code>&lt;meta name="keywords"...&gt;</code> in textarea, and press 'save' key,it generates the error.</p>
  
  <p>Surprizingly, if i write a letter between two line tags like</p>
  
  <p><code>&lt;meta name="description"...&gt;A&lt;meta name="keywords"...&gt;</code>, it accepts again and save it to the database.</p>
  
  <p>I contacted to my admin server and tell about misconfiguration about <code>mod_security</code> settings on the apache server, but they think it is not the problem.</p>
  
  <p>Many thanks</p>
