It's me again :( I was trying to install siwapp on my webserver but I couldn't make it work with nginx, here is the .htaccess file content:

# If the file is NOT the index.php file
<IfModule mod_rewrite.c>

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !index.php
# Hide all PHP files so none can be accessed by HTTP
RewriteRule (.*)\.php$ index.php/$1


RewriteCond $1 !^(index\.php|nhototamsu|assets|cache|xd_receiver\.html|photo|ipanel|automap|xajax_js|files|robots\.txt|favicon\.ico|ione\.ico|(.*)\.xml|ror\.xml|tool|google6afb981101589049\.html|googlec0d38cf2adbc25bc\.html|widget|iradio_admin|services|wsdl)

RewriteRule ^(.*)$ index.php/$1 [QSA,L]



</IfModule>


When I access http://myurl.com/tin-tuc/tuyen-sinh/tu-van/2012/04/25757-phan-van-qua-giua-khoi-a1-va-khoi-a.html ,nginx could display the page correctly, it said: "404 Not Found" (new URL: http://myurl.com/tin-tuc/tuyen-sinh/tu-van/2012/04/25757-phan-van-qua-giua-khoi-a1-va-khoi-a.html)
