title: htaccess not working in sub-directory
body: <p>i have a vhosts in ubuntu, i work fine except the .htaccess in a sub-folder (images folder) is not work. </p>
  
  <p>The problem is, I have written a .htaccess file in the sub-folder, and even I typed some thing wrong syntax .htaccess, it does not response error,i am pretty sure that the .htaccess in subfolder is being ignored.
   i think that some setting is needed to let apache beware of the .htaccess in sub-folder, any one can help?</p>
  
  <p>my system is ubuntu</p>
