mod_rewrite is just possibly one of the most useful Apache modules and features. The ability to rewrite requests internally as well as externally is extremely powerful.

.htaccess rewrite examples should begin with:

1. Require the www
2. Require no www
3. Check for a key in QUERY_STRING
4. Removes the QUERY_STRING from the URL
5. Fix for infinite loops
6. Redirect .php files to .html files (SEO friendly)
7. Redirect .html files to actual .php files (SEO friendly)
8. block access to files during certain hours of the day
9. Rewrite underscores to hyphens for SEO URL
10. Require the www without hardcoding
11. Require no subdomain
12. Require subdomain
13. Redirecting Wordpress Feeds to Feedburner
14. Only allow GET and PUT request methods
15. Prevent Files image/file hotlinking and bandwidth stealing
16. Stop browser prefetching
17. Make a prefetching hint for Firefox.

Be aware that mod_rewrite (RewriteRule, RewriteBase, and RewriteCond) code is executed for each and every HTTP request that accesses a file in or below the directory where the code resides, so it’s always good to limit the code to certain circumstances if readily identifiable.
