使用Wordpress Rewrite或.htaccess重写URL

I'm trying to append to wordpress an additional parameter into my URL. For example, I have the URL: http://example.com I want to change that to URL: http://example.com/this-example/

I'm thinking I can do this is in htaccess along the lines of a rewrite condition, but i'm unsure how to go about this. This is what I was thinking here.

Htaccess

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteEngine on
RewriteRule ^/this-example/(.*)/ /index.php?$1 [L]
</IfModule>
Options -Indexes

You can try this:

<IfModule mod_rewrite.c>
    RewriteEngine on
    RewriteCond %{THE_REQUEST} !^/this-example [NC]
    # use your own host here, for me is 192.68.10.10
    RewriteCond %{HTTP_HOST} 192\.168\.10\.10$ [NC] 
    RewriteRule !^this-example/ /this-example%{REQUEST_URI} [L,R,NE]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^this-example/(.*)$ $1 [L,QSA]
</IfModule>

Options -Indexes
