The WordPress XML-RPC API has been under attack for many years now. Back in August 2014, WordPress released version 3.9.2, fixing a possible denial of service issue in PHP’s XML processing. There are brute-force amplification attacks, reported by Sucuri, and so on. So, how do you protect WordPress from xmlrpc.php attacks, but still being able to use (some of) its functionality like Jetpack? This post gives you some insight.

Jim Walker from HackRepair.com posted a 2016 version of his Bad Bots .htaccess on Pastebin. I offered Jim to translate his Bad Bots .htaccess to web.config, to be used with Windows Server IIS. And here it is, learn to protect your WordPress website with this web.config file!
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. We needed to match our website and proxy those requests to the new IIS web server. This can either be done using a proxy with URL Rewrite, IIS Application Request Routing (ARR), or a .htaccess file handled by Helicon Ape.
The Baidu spider (BaiduSpider user agent) can be a real pain to block, especially since it does not respect a robots.txt as it should. This post shows you how to block Baidu Spider bot, using IIS URL Rewrite Module based on its User-Agent string.

I often receive questions about how to use a web.config file in WordPress on Windows Server, and which settings are important for a WordPress site. Maybe it’s because I’m a WordPress on IIS enthusiast, so here is my web.config for your convenience (really, it’s not that special).

The following PHP function secures your WordPress website by disabling the execution of PHP scripts in wp-content/uploads, on Windows Server IIS web servers. It creates a web.config file for this purpose.
An HTTP to HTTPS redirect on IIS is often better left to the web server, with a simple httpRedirect redirection, than to a resource expensive URL Rewrite. This is easily done in a web.config IIS website configuration file. Where possible, use the IIS httpRedirect element for a HTTP to HTTPS redirection, and here is how:

Remove HTTP response headers in IIS 7, 7.5, 8.0, 8.5, 10 and ASP.NET
Windows Server IIS loves to tell the world that a website runs on IIS. It does so with the Server header in the HTTP response, as shown below. In this post I’ll show you how to remove response server headers in IIS. You don’t want to give hackers too much information about your servers, heh? ;-).

This is also known as IIS with URL Rewrite as a reverse proxy, and should improve website performance. Just recently I noticed Outbound Rules conflicted with gzip compressed content. The following HTTP 500.52 URL Rewrite Module Error was thrown:
The less spammers hit your WordPress blog, the better your blog performs, is one of my opinions. A second is, the less unnecessary plugins you use on your WordPress blog, the better. So, a little while ago I decided to remove plugins like Stop Spammer Registration Plugin and do its work myself. Here is why & how:
Continue readingThis website Saotn.org is hosted on Windows Server 2012 with IIS 8.0 with WordPress for a few months now, and everything is running very smooth. And I would never hit this bug because I don’t need to change my permalinks structure, or save any other plugin setting which would want write to a web.config file. One of my colleagues on the other hand, just moved his website to one of our IIS 8.0 web servers and he noticed he couldn’t save his Permalinks structure in the IIS web.config file. This can be pretty annoying 😉 Quick fix attached…
