RewriteProxy with .htaccess in IIS

Rewrite and proxy HTTP requests in IIS using a .htaccess. In my case scenario, I had to proxy requests in IIS, because a website was moved from web server A to B, and the DNS wasn't updated yet. All HTTP requests for the moved website are handled in IIS' Default Web Site; that's the wildcard host, and the original host no longer existed there.

This can either be done using a proxy with IIS URL Rewrite, IIS Application Request Routing (ARR), or a .htaccess file handled by Helicon Ape.

Add a delay to your WordPress login form

This plugin adds a three second delay when logging into WordPress. This slows down brute-force attacks on your website. However, it is not recommended to use sleep(), because a heavy brute-force attack will let all those POST requests sleep for the given amount of time.
