Block Random String Comment Spam

Recently WordPress sites have been getting hammered with random-string comment spam. The attackers are clever, using random text strings for every vector except the payload, which usually is the URL used for the comment’s Name link. But for these weird comment spams, the apparent payload is the email address. It’s the only part of the comment that’s not made up of random gibberish. Continue reading »

DIY Server Uptime Monitor

There are many free (and commercial) uptime monitoring services that will alert you if your server goes offline. These services are popular because it’s mission critical to know when your sites are down. The sooner you know about it, the sooner you can scramble to get everything back online. I’ve tried other scripts and services but nothing that met my specific needs: simple, secure, lightweight and blazing fast. So decided roll my own DIY server status monitor and share it […] Continue reading »

Redirect Stupid Bots to Existing Resources

In case you hadn’t noticed, I’m on another one of my posting sprees. Going through the past year’s worth of half-written drafts and collected code snippets, and sharing anything that might be useful or interesting. Here is a bit of .htaccess that brings together several redirection techniques into a singular plug-&-play code snippet. Continue reading »

Simple Request Router via PHP and Apache/.htaccess

I’ve written many articles about how to redirect requests. Even so, I still get questions about how to set up a simple HTTP request router. As in you want to redirect or route all requests to some file or location. This is useful for building CMSs and scripts that handle traffic. For example, WordPress uses a simple request router when permalinks are enabled. For this tutorial, we’ll set this up using Apache/.htaccess and PHP. Continue reading »

Enabling ModSecurity (Updated)

For years, I’ve not used ModSecurity for any of my own sites. Way back when I first tried ModSecurity, there were just too many false positives, so I stayed away from it, opting instead to develop my own fast Apache/.htaccess firewall. But my web host now is telling me that ModSecurity is required on all of their managed VPS plans. Continue reading »

Protect WordPress Media Files

[ Protect WordPress Media Files ]

This is an experimental technique that I am playing with. It’s the simplest possible way that I could think of to protect all files in the WordPress Media Library using only Apache/.htaccess. I’ve been testing the code on an image-heavy site and so far there are no issues. So I want to put the code out there for others to test and hopefully provide feedback if anything less than perfect. It’s a super simple method that prevents media files from […] Continue reading »

Opt Out of Google FLOC for Site Visitors (One Line of Code)

Floc of Sheep

Google has another new thing they are doing, called FLOC (Federated Learning of Cohorts). It’s used to — surprise — track user activity across websites. Opting out ideally is handled by the user, who can customize their browser settings to disable FLOC while surfing around the Web. Beyond configuring your browser to opt-out of FLOC, you can disable it on any website with a single line of code. Continue reading »

Disable Apache mod_rewrite Rules in any Subdirectory

Let’s say you have some .htaccess rewrite rules in place using Apache’s mod_rewrite. By default if the rewrite rules are located in the root directory, they will be applied to every subdirectory, as expected. But what if you need to disable the rewrite rules so that they do not affect some specific sub-directory or sub-folder? This super quick tutorial shows the easiest way to do it. Continue reading »

7G Firewall for Nginx

7G Nginx

After several months of development, the official Nginx version of the 7G Firewall is out of beta and ready for public use. If you are not familiar with 7G Firewall, check out the documentation for the Apache/.htaccess version. The Nginx version of the 7G Firewall works the exact same way, so I won’t bother repeating everything here. The only difference is the implementation, how to set it up on an Nginx server, which is explained in this post. Continue reading »

BBQ Firewall is a lightweight, super-fast plugin that protects your site against a wide range of threats. BBQ checks all incoming traffic and quietly blocks bad requests containing nasty stuff like eval(, base64_, and excessively long request-strings. This is a simple yet solid solution for sites that are unable to use a strong Apache/.htaccess firewall. Continue reading »

Remove or Hide File Extension with .htaccess

A common question I get is how to change or hide file extensions using .htaccess. Apparently search engines prefer “pretty” permalink URL structures over query-strings and file extensions. This is one reason why WordPress provides an SEO-friendly permalink option for URLs; because it is preferred over the default plain query-string based format. From the Permalinks settings screen in the WordPress Admin Area: Continue reading »
