.htaccess 101
Since I moved my blog to the self hosted domain I said I will write my .htaccess file, especially for the mod_rewrite rules; you know, create a simple WAF. Well that didn’t work out, or better said I was too lazy till know to do it.
Anyway, you’re came here for other reasons. I found today a comprehensive article on .htaccess files, which you can (and highly recommend) read it here. Also you might be interested in a mod rewrite cheat sheet and a regular expression cheat sheet.
