.htaccess重定向和可见URL

Question

I'm new to htaccess and I want to know how can I do this two things and if they are recommended or if is there another better way to achieve a SEO friendly and nice URL:

1. Redirect from www.example.com/products?id=car to example.com/car . If you can tell me the best method for SEO friendly it would be great (301 or whatever).
2. Show always the url example.com/car as a pretty url and not with symbols, even when clicking a link that redirects to www.example.com/products?id=car.

Answer 1

You can use this code in your DOCUMENT_ROOT/.htaccess file:

RewriteEngine On
RewriteBase /example/

# external redirect from actual URL to pretty one
RewriteCond %{THE_REQUEST} /products(?:\.php)?\?id=([^\s&]+) [NC]
RewriteRule ^ %1? [R=302,L,NE]

# internal forward from pretty URL to actual one
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/?$ products.php?id=$1 [L,QSA]
