This past week I updated my sites apache.css file for a site-redesign. I wanted to make changes to the .css file that only I could see, so that my regular traffic and site-visitors would still see the old version. Here's the elegant solution I came up with using .htaccess and mod_rewrite that works so well I'm sharing it with all you wonderful and incredible people reading my blog :)

I've had a lot of people ask about the FeedBurner FeedCount image on AskApache. Specifically how to set it up with custom messages and different colors each page view... It is pretty sweet..
Hacking Feed Count FeedBurner Htaccess
This is all new, experimental, and very very cool. It literally uses .htaccess techniques to create several virtual "locked gates" that require a specific key to unlock, in a specific order that cannot be bypassed. It uses whitelisting .htaccess tricks to specify exactly what is allowed, instead of trying to specify everything that isn't allowed. Also, by setting specific cookies/tokens after successfully passing through a gate, we can then require the exact cookie/token from the previous gate, which stops an attacker from skipping or bypassing gates.

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.

The bottom line for this article is that I want to make WordPress as fast, secure, and easy to install, run, and manage because I am using it more and more for client production sites, I will work for days in order to solve an issue so that I never have to spend time on that issue again. Time is money in this industry and that is ultimately (time) what there is to gain by tweaking WordPress.
Note: I spent no time on readability, this is primarily a read the code and figure it out article.. This is for advanced users looking for a reference or discussion and for those of you looking to advance. Feedback would be great if you make it that far..

So my blog as been rather quiet for almost a year now, and very few updates if any have been released for my Password Protection PLugin, my Google 404 Plugin, and definately not for my AskApache CrazyCache plugin, which I will be releasing last... So for all of you who've helped me out by sending me suggestions and notifying me of errors and sticking with it... Just wanted to say sorry about that, and thanks for all the great ideas.. Well, I've been sticking with it as well believe it our not. I manage to get free days once in a while, and then its time to jam.

What if you'd like to send a 200 OK response instead of the default 404 Not Found response using Apache .htaccess files or httpd.conf? One use would be to make sure upstream caches cache any request on an api server, as 404's are not cached.
