Rewrite Query String into Plain URL

  • Apache

As you may already know that URLs are always the shorter the better for both visitors and search engines to understand your web pages at a glance. Therefore, the plain URLs should be better than the URLs with a long query string.

For example, we would like the directory-based URL:


to replace the long dynamic parameters:


In such case, we can use Apache Rewrite to implement the plain URL by modifying /etc/httpd/conf/http.conf.

[root@test ~]# vi /etc/httpd/conf/httpd.conf
    RewriteEngine On
    RewriteCond %{QUERY_STRING} ^$  # Without any query string
    RewriteRule ^(.+)/(.+)/(.+)/?$ products.php?class=$1&subclass=$2&name=$3 [B,NC,L]

In another words, we use the dynamic page in the background:


To process the URI pattern:


As you can see, there's no any query string and looks more like a natural string in the foreground.

Please test your web pages after restarting Apache httpd. For more syntax and examples, you may refer to the documentation:
