Bluehost, Sitelock, SSL, and .htaccess

[ Box Hole ]

Apparently, Bluehost partnered with a company called SiteLock sometime last year. Supposedly Sitelock is a “website scanner that proactively checks for malicious threats and vulnerabilities”. I guess the service operates on Bluehost servers, and today they sent a scary email letting me know that “malware was detected” on my Bluehost site. Here’s the thing though. I host only one site at Bluehost, and it is a simple one-page site with only a few simple files. So I was surprised by […] Continue reading »

Difference between mod_alias and mod_rewrite

Most of the redirect techniques provided in my stupid .htaccess tricks article all use Apache’s alias module, mod_alias. You can also use mod_rewrite to redirect URLs. The main difference is that, with mod_alias, the server is responding to the client request with a redirect, so the client immediately is sent to the new location. Conversely, with mod_rewrite, the server simply returns the new content, so the client is not actually redirected anywhere. This makes mod_rewrite more advantageous because it happens […] Continue reading »

.htaccess Cleanup

Once again I am cleaning up my sites’ .htaccess files. I do this from time to time to remove old redirects, refresh blacklists, and update security and SEO-related directives. It’s tedious work, but the performance and security benefits make it all worthwhile. This post shares some of the techniques that were added, removed, or replaced from .htaccess, and explains the reasoning behind each decision. I do this for the sake of reference, and hopefully it will give you some ideas […] Continue reading »

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> When placed in the web-accessible root directory’s htaccess file, that snippet will ensure that all requests for your site are not prefixed with www. There’s […] Continue reading »

HTAccess Spring Cleaning 2009

Just like last year, this Spring I have been taking some time to do some general maintenance here at Perishable Press. This includes everything from fixing broken links and resolving errors to optimizing scripts and eliminating unnecessary plugins. I’ll admit, this type of work is often quite dull, however I always enjoy the process of cleaning up my HTAccess files. In this post, I share some of the changes made to my HTAccess files and explain the reasoning behind each […] Continue reading »

PHP Short Open Tag: Convenient Shortcut or Short Changing Security?

[ Echo Shortcut Code ]

Most of us learned how to use “echo()” in one of our very first PHP tutorials. That was certainly the case for me. As a consequence, I never really had a need to visit PHP’s documentation page for echo(). On a recent visit to Perishable Press, I saw a Tumblr post from Jeff about the use of PHP’s shortcut syntax for echo() but somewhere deep in my memory, there lurked a warning about its use. I decided to investigate. Continue reading »

Perishable Press HTAccess Spring Cleaning, Part 2

[ Spring Cleaning ]

Before Summer arrives, I need to post the conclusion to my seasonal article, Perishable Press HTAccess Spring Cleaning, Part 1. As explained in the first post, I recently spent some time to consolidate and optimize the Perishable Press site-root and blog-root HTAccess files. Since the makeover, I have enjoyed better performance, fewer errors, and cleaner code. In this article, I share some of the changes made to the blog-root HTAccess file and provide a brief explanation as to their intended […] Continue reading »

Perishable Press HTAccess Spring Cleaning, Part 1

[ Psychedelic Blossom ]

While developing the 3G Blacklist, I completely renovated the Perishable Press site-root and blog-root HTAccess files. Since the makeover, I have enjoyed better performance, fewer errors, and cleaner code. In this article, I share some of the changes made to the root HTAccess file and provide a brief explanation as to their intended purpose and potential benefit. In sharing this information, I hope to inspire others to improve their own HTAccess and/or configuration files. In the next article, I will […] Continue reading »

Improve Site Performance by Increasing PHP Memory for WordPress

During the recent ASO server debacle, I raced frantically to restore functionality to Perishable Press. Along the way, one of the many tricks that I tried while trying to fix the dreaded “white screen of death” syndrome involved increasing the amount of PHP memory available to WordPress. This fix worked for me, but may not prove effective on every installation of WordPress. If you are unsure as to whether or not you need to increase your PHP memory, consult with […] 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 »

Optimize WordPress: Pure Code Alternatives for 7 Unnecessary Plugins

[ Photo: Macro shot of a Yttrium claw ]

In this article, my goal is to help you optimize WordPress by replacing a few common plugins with their correspondingly effective code equivalents. As we all know, WordPress can be a very resource-hungry piece of software, especially when running a million extraneous plugins. Often, many common plugins are designed to perform relatively simple tasks, such as redirect a feed, display a random image, query the database, etc. For those of us comfortable with editing PHP and htaccess code, there is […] Continue reading »

How to Block IP Addresses with PHP

[ Image: Skeletor Blocks a Move ]

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 »

Major Problem with cPanel Hotlink Protection and htaccess

[ Image: Train Wreck ]

There is a major problem with the “Hotlink Protection” feature of cPanel. To summarize the issue, allow me to quote a recent email sent to a completely unresponsive tech support department: …The problem is that if I try to include any rewrite rules for permalinks, hotlinking, or blocking spambots, cPanel automatically enables its “Hotlink Protection” feature. And, even worse, it automatically adds every URL from every rewrite rule (even the ones for blocking spambots) to its “auto-discovered” list of URL’s […] Continue reading »

Compressed JavaScript Compression

In this article, we extrapolate our favorite CSS-compression technique for JavaScript. Below, we outline the steps required to auto-compress your JavaScript documents via gzip and PHP. Two different compression methods are presented. The first method does not require htaccess, but rather involves the manual editing of JavaScript files. The second method employs htaccess to do all the work for you, thus requiring much less effort to implement. In either case, the result is the same: automatically compressed content delivered only […] Continue reading »
