![[ Server Mayhem ]](https://perishablepress.com/wp/wp-content/images/2007/misc-chunks/server-mayhem.jpg)
Just when I thought I had finally solved my web-hosting woes by transferring to a virtual private server, I am slapped in the face by the cold realities of server memory limitations. Apparently, WordPress-powered sites are extremely resource-intensive, requiring insane amounts of random access memory (RAM), something which does not concern those of us working from shared hosting accounts. On a shared server, system resources are shared among the various accounts that reside on a particular server. When one of […] Continue reading »
..And we’re back. After an insane week spent shopping for a new host, dealing with some Bad Behavior, and transferring Perishable Press to its new home on a virtual private server (VPS), everything is slowly falling back into place. Along the way, there have been some interesting challenges and many lessons learned. Here are a few of the highlights.. Continue reading »
Hello! If you are seeing this page via the default WordPress theme (i.e., blue header, based on Kubrick), welcome to the new server! I recently upgraded my hosting to a virtual private server, and finally reassigned the domain name servers to resolve to the new address. So, if you are here and everything seems to be working, then everything went according to plan and I will be able to complete the transfer on Saturday (Lord willing). If, on the other […] Continue reading »
Hello! As many of you already know, the popular WordPress anti-spam plugin, Bad Behavior, caused some problems yesterday, and as a result many bloggers and users were locked out of their favorite sites, including this one. As for now, the problem seems to be fixed, however, the experience of being locked out of my own site has left a rather unpleasant taste in my mouth. Needless to say, I will be reconsidering the continued use of Bad Behavior as a […] Continue reading »
Just a note to let everyone know that Perishable Press will be undergoing site maintenance for the next several hours. I apologize in advance for any inconvenience this might cause. Thanks for your patience ;) Continue reading »
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 »
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 »
Okay, I realize that the title sounds a bit odd, but nowhere near as odd as my recent discovery of Slurp ignoring explicit robots.txt rules and digging around in my highly specialized bot trap, which I have lovingly dubbed “the blackhole”. What is up with that, Yahoo!? — does your Slurp spider obey robots.txt directives or not? I have never seen Google crawling around that side of town, neither has MSN nor even Ask ventured into the forbidden realms. Has […] Continue reading »

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 »

In our original htaccess blacklist article, we provide an extensive list of bad user agents. This so-called “Ultimate htaccess Blacklist” works great at blocking many different online villains: spammers, scammers, scrapers, scrappers, rippers, leechers — you name it. Yet, despite its usefulness, there is always room for improvement. Continue reading »
My apologies for recent periods of site unavailability. Apparently, my hosting company is having a difficult time with the server that happens to host Perishable Press. As far as I can tell, the server problems began Wednesday morning (due to a “traffic spike”). By Thursday morning, Perishable Press (as well as a few of my other sites) had been down for a period exceeding eight nonconsecutive hours. According to my log files, Thursday itself was even worse, with server uptime […] Continue reading »

Most of the time, when I catch scumbags attempting to spam, scrape, leech, or otherwise hack my site, I stitch up a new voodoo doll and let the cursing begin. No, seriously, I just blacklist the idiots. I don’t need their traffic, and so I don’t even blink while slamming the doors in their faces. Of course, this policy presents a bit of a dilemma when the culprit is one of the four major search engines. Slamming the door on […] Continue reading »

Figuratively speaking, hunting down and killing spammers, scrapers, and other online scum remains one of our favorite pursuits. Once we have determined that a particular IP address is worthy of banishment, we generally invoke the magical powers of htaccess to lock the gates. When htaccess is not available, we may summon the versatile functionality of PHP to get the job done. This method is straightforward. Simply edit, copy and paste the following code example into the top of any PHP […] Continue reading »
Web developers trying to control comment-spam, bandwidth-theft, and content-scraping must choose between two fundamentally different approaches: selectively deny target offenders (the “blacklist” method) or selectively allow desirable agents (the “opt-in”, or “whitelist” method). Currently popular according to various online forums and discussion boards is the blacklist method. The blacklist method requires the webmaster to create and maintain a working list of undesirable agents, usually blocking their access via htaccess or php. The downside of blacklisting is that it requires considerable […] Continue reading »
What we have here is an excellent method for preventing a great deal of blog spam. With a few strategic lines placed in your .htaccess file, you can prevent spambots from dropping spam bombs by denying access to all requests that do not originate from your domain. Continue reading »
![[ Stop bitacle.org ]](https://perishablepress.com/wp/wp-content/images/2006/misc-chunks/stop-bitacle.png)
If you have yet to encounter the content-scraping site, bitacle.org, consider yourself lucky. The scum-sucking worm-holes at bitacle.org are well-known for literally, blatantly, and piggishly stealing blog content and using it for financial gains through advertising. While I am not here to discuss the legal, philosophical, or technical ramifications of illegal bitacle behavior, I am here to provide a few critical tools that will help stop bitacle from stealing your content.
