我想重写以下URL：
http://www.web.de/productCat1->将Var productCat1传递到productCat.php
http://www.web.de/productCat1/product20->将Var productCat1+Var product20传递到products.php
http://www.web.de/shop->文件存在时不执行任何操作
http://www.web.de/contact->文件存在时不执行任何操作
到目前为止，我有这个：
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteBase /
# PHP to NO Extension
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteCond %{REQUEST_URI} !/$
RewriteRule ^(.*)$ $1'.php
#catch all products
RewriteCond %{REQUEST_URI} ^/([^/]+/[^/]+)/{0,1}$
RewriteRule ^([^/]+/[^/]+)/{0,1}$ /products.php?rw=1&url=$1/$2 [L,QSA]
#catch all categories
RewriteCond %{REQUEST_URI} !^/(shop|contact)$
RewriteRule ^([^/]+)$ /productCat.php?rw=1&url=$1/$2 [L,QSA]
经过几次尝试，我仍然收到500内部服务器错误。
尝试：
