Htaccess SEO Trends by Google
htaccess vs. httpd.conf
Serving WebP images for PNG and JPG files
One of the biggest speed bottlenecks of sites today are images, specifically unoptimized images or large scaled images. With Apaches Rewrite module we can convert all existing jpegs and png files (and most gifs) to webp, then transparently rewrite them so that a request for img.png from a browser that supports webp will receive img.webp.

Speed Tips: Turn Off ETags
By removing the ETag header, you disable caches and browsers from being able to validate files, so they are forced to rely on your Cache-Control and Expires header.
Automated Folder Backup Shell-Script
This simple unix shell script automatically creates backups of a specific folder at regular hourly, nightly, weekly, and monthly intervals. Instead of the usual method for copying directory trees using tar with fifo, pipes, rsync, or NFS methods this script uses cpio which is much much faster and has cool options like saving m/a/c times, symlinks, relative paths, and weird file names.
Downloading Multiple Files with Curl Simultaneously
Wouldn't it be great if you could use php and curl to download multiple files simultaneously using built-in curl functions? You can!
Manipulating HTTP Headers with htaccess
Apache .htaccess and httpd.conf have the power to send and manipulate HTTP Header Requests like sending P3P privacy headers, Content-Type: UTF-8, Content-Language, etc. The power is immense and you can do some really cool stuff with HTTP Headers!
Getting the Mimetype of an Image with PHP
This is awesome. I was so fed up with trying to find a fail-proof, cross-platform way to find the mime type of an image using PHP that I wrote a quick function that utilizes the same technology as the exif_imagetype, getimagesize, and finfo functions do. Ahh the joys of low-level.
Security Enhancing with htaccess
Securing Subdirectories using unique apache htaccess solutions.
Unicode Character Reference
Just a quick reference to all those delicious unicode characters and how they render on the web‽‽

SEO with Robots.txt
Very nice tutorial dealing with the robots.txt file. Shows examples for google and other search engines. Wordpress robots.txt and phpBB robots.txt sample files.Preload flash .flv files into browser cache
How I was able to preload many flash flv and swf files on one of my clients sites that has a lot of online video and relatively small traffic. Their site visitors would usually watch 3-10 videos per visit and so to make the videos load almost instantly on every page I came up with a way to preload the top 10 .flv files and the swf flv player files as soon as the visitor successfully started watching the 1st video. Of course I also setup .htaccess caching on the server so that once they downloaded the files into their cache they would never request them from the server again. I was having fun with this so its pretty funky and uses some really cool combinations of javascript, swf preloader from xml, css classes to help automate it all..
IP Blocked by stateful Firewall, now what?
Removing Category Base from WordPress URLs
How To remove the /category/ from WordPress category urls.
James
We're using WP as a CMS with pages and posts. Done a bit of customization, so it looks sweet. Problem - i have some child categories that throw 404 when the category redirect is in place. How did you remove the category base from the url structure in wordpress?
Javascript Snippet to Add HTML, CSS, and FEED Validation Links
Here's an example of validation links from the AskApache footer.
RSS | XHTML 1.1 | CSS 2.1
document.getElementById("validat").innerHTML += ' | <a href="http://feedvalidator.org/check.cgi?url=https://www.askapache.com/feed/">RSS</a> | <a href="http://validator.w3.org/check/referer?ss=1;outline=1;sp=1;debug">XHTML 1.1</a> | <a href="http://jigsaw.w3.org/css-validator/check/referer?warning=0">CSS 2.1</a>';
SPF Records on DreamHost
Here are the steps that I take to get an SPF Record going on DreamHost
v=spf1 mx ip4:64.111.100.0/24 ip4:66.33.201.0/24 ip4:66.33.216.0/24 ip4:208.97.1 32.0/24 ip4:208.97.187.0/24 ip4:208.113.200.0/24 ip4:208.113.244.0/24 ip4:64.18.0.0/20 ip4:74.125.148.0/22 include:aspmx.googlemail.com include:_spf.google.com ~all
Custom PHP.ini with FastCGI on DreamHost
I'm really sorry but I had to disable the sites you had running under user $USER because that was the only way I could keep the associated processes from restarting themselves and making the server unstable. Please do not run these sites with a persistent php.cgi process with a php.ini file as an argument.I got hacked
Well, not this sites server, which has never been hacked, but a server hosted with hostgator.
Interestingly, the hacker sent me an email and left me an mp3, which I've uploaded for your listening leisure.
Do real hackers exist? Yes. Can we coexist? Preferably!
Using FilesMatch and Files in htaccess
Some good examples for how to use the Files and FilesMatch directives in .htaccess files and httpd.conf files for Apache.

Crazy Cache WordPress Plugin Released
A WordPress plugin that caches your entire blog for WP-Cache, I love this plugin and finally released it to the public!
Firefox, Firebug, and yslow are REQUIRED
A lot of the past and upcoming articles on AskApache are focused on speeding up a server or website, or just making things more efficient. I'm starting several speed tip articles that require the following 3 programs if you want to follow along, that is... if you can keep up! ;)
Discover who’s tracking you online with Collusion
The collusion add-on for Firefox is super-legit. Just navigate to any website normally, then just click the little collusion icon in the status bar and a full detailed report pops up in a new tab describing all the sites that the current site shared your data with (shared as in connected).
View the full introduction to Collusion on mozilla.org, or view my Firefox Add-on Collection: AskApache Web Development (Advanced)
Encrypted WordPress / phpBB Backups
Enter your DOMAIN_ROOT and the location of your wp-config.php or config.php, and this script finds all the mysql settings by parsing the phpbb or wordpress config file, then creates GPG encrypted backups, and saves your settings for future automation.
Language/Country specific Google Search Engine's
Google's Search Engine Hosting Servers automatically provide Internet users all over the world with a "localized" version of the incredible Google Search Engine that we know and love.
Speed Tips: Add Cache-Control Headers
Using Cache-Control headers you can specify which types of proxies can cache certain content, and how long files should be cached.
PHP fsockopen for FAST DNS lookups over UDP
While reading up on gethostbyaddr on PHP.net, I saw a nice idea for using fsockopen to connect over UDP port 53 to any Public DNS server, like Google DNS 8.8.8.8, and sending the reverse addr lookup in oh about 100 bytes, then getting the response in oh about 150 bytes! All in less than a second. This is how/why to read/write data directly to the wire! This would be extremely valuable for use in things like my online header tool because it's faster than any other method. As usual, I went a bit overboard optimizing it to be lean and fast.
Htaccess Rewrite for Redirecting Uppercase to Lowercase
Want to redirect all links with any uppercase characters to lowercase using pure mod_rewrite within an .htaccess file? Sure why not! OR how to use RewriteMap and mod_speling for those with access to httpd.conf
Alternate robots.txt files with Htaccess
So here's the basic idea: There are 2 sites, a development site and a live site. They are essentially mirrors of each other in terms of they have the same files. You need to disallow all search engine robots from indexing and crawling the development site, while allowing full crawling of your live site. Htaccess to the rescue!
Adding a Trailing "/" to WordPress Permalinks
Problem: WordPress shows pages, categories, author pages, etc. without an ending '/'.
/about instead of /about/.
/category/htaccess instead of /category/htaccess/.
Solution: Either hook into the user_trailingslashit filter, or use some htaccess RedirectMatch
phpMyAdmin Shortcuts with .htaccess
Use mod_rewrite to enable phpMyAdmin links in the form: /dbname/table/
