Universal www-Canonicalization via htaccess

[ Universal www-Canonicalization via htaccess ]

During my previous rendezvous involving comprehensive canonicalization for WordPress, I offer my personally customized technique for ensuring consistently precise and accurate URL delivery. That particular method targets WordPress exclusively (although the logic could be manipulated for general use), and requires a bit of editing to adapt the code to each particular configuration. In this follow-up tutorial, I present a basic www-canonicalization technique that accomplishes the following: Continue reading »

Welcome to the Perishable Press “Blacklist Candidate” series. In this post, we continue our new tradition of exposing, humiliating and banishing spammers, crackers and other worthless scumbags.. Since the implementation of my 2G Blacklist, I have enjoyed a significant decrease in the overall number and variety of site attacks. In fact, I had to time-travel back to March 1st just to find a candidate worthy of this month’s blacklist spotlight. I felt like Rod Roddy looking over the Price-is-Right audience […] Continue reading »

Welcome to the Perishable Press “Blacklist Candidate” series. In this post, we continue our new tradition of exposing, humiliating and banishing spammers, crackers and other worthless scumbags.. Imagine, if you will, an overly caffeinated Bob Barker, hunched over his favorite laptop, feverishly scanning his server access files. Like some underpaid factory worker pruning defective bobble heads from a Taiwanese assembly line, Bob rapidly identifies and isolates suspicious log entries with laser focus. Upon further investigation, affirmed spammers, scrapers and crackers […] Continue reading »

2G Blacklist: Closing the Door on Malicious Attacks

[ 2G Blacklist ]

Since posting the Ultimate htaccess Blacklist and then the Ultimate htaccess Blacklist 2, I find myself dealing with a new breed of malicious attacks. It is no longer useful to simply block nefarious user agents because they are frequently faked. Likewise, blocking individual IP addresses is generally a waste of time because the attacks are coming from a decentralized network of zombie machines. Watching my error and access logs very closely, I have observed the following trends in current attacks: Continue reading »

Over 150 of the Worst Spammers, Scrapers and Crackers from 2007

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, nefarious attackers for blacklisting. Minor offenses are generally dismissed, but the evil bastards that insist on wasting resources running redundant automated scripts are immediately investigated […] Continue reading »

Welcome to the Perishable Press “Blacklist Candidate” series. In this post, we continue our new tradition of exposing, humiliating and banishing spammers, crackers and other worthless scumbags.. Like many bloggers, I like to spend a little quality time each week examining my site’s error logs. The data contained in Apache, 404, and even PHP error logs is always enlightening. In addition to suspicious behavior, spam nonsense, and cracker mischief, this site frequently endures automated and even manual attacks targeting various […] Continue reading »

Permalink Evolution: Customize and Optimize Your Dated WordPress Permalinks

How to streamline and maximize the effectiveness of your WordPress URLs by using htaccess to remove extraneous post-date information: years, months, and days.. Recently, there has been much discussion about whether or not to remove the post-date information from WordPress permalinks1. Way back during the WordPress 1.2/1.5 days, URL post-date inclusion had become very popular, in part due to reports of potential conflicts with post-name-only permalinks. Throw in the inevitable “monkey-see, monkey-do” mentality typical of many bloggers, and suddenly an […] Continue reading »

Comprehensive URL Canonicalization via htaccess for WordPress-Powered Sites

[ Secrets Revealed! ]

Permalink URL canonicalization is automated via PHP in WordPress 2.3+, however, for those of us running sites on pre-2.3 versions or preferring to deal with rewrites directly via Apache, comprehensive WordPress URL canonicalization via htaccess may seem impossible. While there are several common methods that are partially effective, there has not yet been available a complete, user-friendly solution designed specifically for WordPress. Until now.. In this article, I share my “secret” htaccess URL canonicalization formula. I originally developed this method […] Continue reading »

Welcome to the Perishable Press “Blacklist Candidate” series! In this first post, we begin a new tradition of exposing, humiliating and banishing spammers, crackers and other worthless scumbags.. Every Wednesday, I take a little time to investigate my 404 error logs. In addition to spam, crack attacks, and other deliberate mischief, the 404 logs for Perishable Press contain errors due to missing resources, mistyped URLs, and the occasional bizarre or even suspicious behavior of the search-engine robots. Whenever possible, I […] Continue reading »

How to Enable PHP Error Logging via htaccess

In this brief tutorial, I will show Apache users how to suppress PHP errors from visitors and enable PHP error logging via htaccess. Tracking your site’s PHP errors is an excellent way to manage and troubleshoot unexpected issues related to plugins and themes. Even better, monitoring PHP errors behind the scenes via private log is far better than trying to catch them as they appear at random visits. Thanks to the magical powers of htaccess, there is an easy way […] Continue reading »

Three Ways to Allow Hotlinking in Specific Directories

After implementing any of the hotlink-prevention techniques described in our previous article, you may find it necessary to disable hotlink-protection for a specific directory. By default, htaccess rules apply to the directory in which it is located, as well as all subdirectories contained therein. There are (at least) three ways to enable selective hotlinking: Place hotlink images in an alternate directory This method works great if your hotlink-protection rules are located in a directory other than the site root. Simply […] Continue reading »

Stupid htaccess Trick: Enable File or Directory Access to Your Password-Protected Site

In this brief tutorial, we are going to enable users to access any file or directory of a site that is password-protected via htaccess. There are many reasons for wanting to employ this technique, including: Share public resources from an otherwise private site Enable visitors to access content during site maintenance Testing and formatting of layout and design during development As a webmaster, I have used this technique on several occasions. This trick works great for allowing access to any […] Continue reading »

Creating the Ultimate .htaccess Anti-Hotlinking Strategy

[ Image: Illustration of two hands holding a glowing object ]

When I wrote my article, Stupid htaccess Tricks, a couple of years ago, hotlink-protection via htaccess was becoming very popular. Many webmasters and bloggers were getting tired of wasting bandwidth on hotlinked resources, and therefore turned to the power of htaccess to protect their content. At that time, there were only a couple of different hotlink-protection methods available on the internet, and the functional difference between them was virtually insignificant. All that was necessary for up-and-coming bloggers-slash-site-administrators to eliminate leaking […] Continue reading »
