is it possible 2 rewrite rules in .htaccess file ?

[arielcon]

Hi friends,
Please can someone help me with this trouble ?

I've this website related to Notebooks, http://www.tiendanotebooks.com.ar and the directory software has a rewrite rule who is working well.

• current .htaccess file:

  RewriteEngine On
  
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-l
  RewriteRule ^(.*)$ index.php [QSA,L]
  

  I want to replace the visible url links to the page item.php.
  
  I need to add a new rule to cath all my friendly pages like NOTEBOOK_Acer_Aspire.HTML to the item.php file with 2 parameters :
  
  CURRENT BAD SOLUTION :
  http://www.tiendanotebooks.com.ar/item.php?d=Hp_550_Notebook_Compaq_4gb_Core_2_Duo_1 20gb_Wifi_Graba_Cd%2FDv&site=MLA&itemid=49334563
  
  New GOOD option 1:
  http://www.tiendanotebooks.com.ar/Hp_550_Notebook_Compaq_4gb_Core_2_Duo_120gb_Wifi_G raba_Cd%2FDv&site=MLA&itemid=49334563
  
  
  New GOOD option 2 with html extension:
  http://www.tiendanotebooks.com.ar/Hp_550_Notebook_Compaq_4gb_Core_2_Duo_120gb_Wifi_Graba_Cd%2FDv.html&site=MLA&itemid=49334563
  
  
  Is it possible to improve that ? My question is bassed on the point that my site already has a rule, who redirects all the posts to index.php file.
  
  Thanks ,
  Ariel
