Optimizing WordPress Permalinks with htaccess

Okay, so Summer’s over, kids are back in school, and I’m finding all sorts of free time to continue writing and posting. One of my Summer projects involved updating & optimizing one of my old project sites, DeadLetterArt.com. It was basically a huge clean-up session that included lots of content consolidation and permalink restructuring. So […] Continue »

Huge Collection of Code Snippets: HTAccess, PHP, WordPress, jQuery, HTML, CSS

Please excuse this self-serving, miscellaneous post, but I’ve just got to purge all of these code snippets and scraps collected over the years. Whenever I update this site, I place any removed/unused code snippets into a giant note file for future reference, just in case. There’s all sorts of different types of code and snippets […] Continue »

Block Tough Proxies

If you want to block tough proxies like hidemyass.com, my previously posted .htaccess methods won’t work. Those methods will block quite a bit of proxy visits to your site, but won’t work on the stealthier proxies. Fortunately, we can use a bit of PHP to keep them out. Continue »

Upload Large Files or Die Trying

I recently spent some time wrestling with various e-commerce/shopping-cart/membership plugins. One of them was of course the popular WP e-Commerce plugin, which uses a directory named “downloadables” to store your precious goods. I had some large files that needed to go into this folder, but the server’s upload limit stopped me from using the plugin’s […] Continue »

Humans.txt

One thing I love about Twitter is the instant feedback. For the past few weeks I’ve been seeing lots of 404 requests like this: https://perishablepress.com/humans.txt https://perishablepress.com/humans.txt https://perishablepress.com/humans.txt At first I thought it was some skript kiddie getting creative, you know as a play on the robots.txt file, which is also located in the root of […] Continue »

Clean Up Malicious Links with HTAccess

I recently spent some time analyzing Perishable Press pages as they appear in the search results for Google, Bing, et al. Google Webmaster Tools provides a wealth of information about crawl errors, as well as the URLs of any pages that link to missing content. Combined with your site’s access/error logs, you have everything needed […] Continue »

5G Firewall Beta

Updating the 4G Blacklist, the new 5G Firewall is now open for beta testing. The new code is better than ever, providing wider protection with less code and fewer false positives. I’ve had much success with this new firewall, but more testing is needed to ensure maximum compatibility and minimal issues. Continue »

Canonical URLs and Subdomains with Plesk

I am in the process of migrating my sites from A Small Orange to Media Temple. Part of that process involves canonicalizing domain URLs to help maximize SEO strategy. At ASO, URL canonicalization required just a few htaccess directives: # enforce no www prefix <ifmodule mod_rewrite.c> RewriteCond %{HTTP_HOST} !^domain\.tld$ [NC] RewriteRule ^(.*)$ http://domain.tld/$1 [R=301,L] </ifmodule> […] Continue »

Latest Blacklist Entries

Recently cleared several megabytes of log files, detecting patterns, recording anomalies, and blacklisting gross offenders. Gonna break it down into three sections: User Agents Character Strings IP Addresses User Agents User-agents come and go, and are easily spoofed, but it’s worth a few lines of htaccess to block the more persistent bots that repeatedly scan […] Continue »

How to Deal with Content Scrapers

Chris Coyier of CSS-Tricks recently declared that people should do “nothing” in response to other sites scraping their content. I totally get what Chris is saying here. He is basically saying that the original source of content is better than scrapers because: it’s on a domain with more trust. you published that article first. it’s […] Continue »

2010 User-Agent Blacklist

The 2010 User-Agent Blacklist blocks hundreds of bad bots while ensuring open-access for the major search engines: Google, Bing, Ask, Yahoo, et al. Blocking bad user-agents is an effective addition to any security strategy. It works like this: your site is getting hammered by rogue bots that waste valuable server resources and bandwidth. So you […] Continue »

Protect Your Site with a Blackhole for Bad Bots

One of my favorite security measures here at Perishable Press is the site’s virtual Blackhole trap for bad bots. The concept is simple: include a hidden link to a robots.txt-forbidden directory somewhere on your pages. Bots that ignore or disobey your robots rules will crawl the link and fall into the honeypot trap, which then […] Continue »

htaccess Code for WordPress Multisite

For the upcoming Digging into WordPress update for WordPress 3.0, I have been working with WordPress’ multisite functionality. Prior to version 3.0, WordPress came in two flavors: “original” and “multisite” (MU). Most designers probably work with regular, one-blog installations of “regular” WordPress. The htaccess rules for all single-blog installations of WordPress haven’t changed. They are […] Continue »

2010 IP Blacklist

Over the course of each year, I blacklist a considerable number of individual IP addresses. Every day, Perishable Press is hit with countless numbers of spammers, scrapers, crackers and all sorts of other hapless turds. Weekly examinations of my site’s error logs enable me to filter through the chaff and cherry-pick only the most heinous, […] Continue »

htaccess Redirect to Maintenance Page

Redirecting visitors to a maintenance page or other temporary page is an essential tool to have in your tool belt. Using HTAccess, redirecting visitors to a temporary maintenance page is simple and effective. All you need to redirect your visitors is the following code placed in your site’s root HTAccess: # MAINTENANCE-PAGE REDIRECT <ifmodule mod_rewrite.c> […] Continue »

Stop 404s for Mobile Versions of Your Site

If you’ve been keeping an eye on your 404 errors recently, you will have noticed an increase in requests for nonexistent mobile files and directories, especially over the past year or so. The scripts and bots requesting these files from your server seem to be looking for a mobile version of your site. Unfortunately, they […] Continue »
