Blocking users or sites that originate from a particular domain is another useful trick of .htaccess. Lets say you check your logs one day, and see tons of referrals from a particular site, yet upon inspection you can’t find a single visible link to your site on theirs. The referral isn’t a “legitimate” one, with the site most likely hot linking to certain files on your site such as images, .css files, or files you can’t even make out.

Why PHPSuExec and the security hole of PHP
On most Apache servers, PHP runs as an Apache Module. As such, it runs directly in the user Nobody, but doesnt require the execute flag. This means that in order to execute a PHP file, it simply needs to be world readable. The problem is that this allows every other users on the server to read your PHP files!

Allowing other users to read your HTML files is not a problem, since they can be displayed in Internet Explorer. However, PHP files are not readable, they are parsed.
