AskApache Password Protection 4.7 Update in 2 Weeks

I am now about 1 week away from publishing the much-anticipated 4.7 update to the AskApache Password Protection WordPress plugin. It's an upgrade I've been working on for almost 2 years (off and on)! I have been using the new version for quite some time now, and have made a lot of improvements to it, and finally I decided enough users have suffered with the old version. I am very excited for this release, it fixes all known bugs in the older versions, and brings some heavy-duty improvements to all facets of this plugin.. not to mention way better security modules (Lots more COOKIE use) based on code I use with clients.

Actual Htaccess Files from My Server

#### No https except to wp-admin -
# If the request is empty ( implies fopen or normal file access by a php script )
RewriteCond %{THE_REQUEST} ^$ [OR]

# OR if the request if for wp-admin or wp-login.php
RewriteCond %{REQUEST_URI} ^/(wp-admin|wp-login\.php).*$ [NC,OR]

# OR if the Referer is https
RewriteCond %{HTTP_REFERER} ^https://www.askapache.com/.*$ [NC]

# THEN skip the following rule, basically all this does is force https or badhost to be redirected
# BUT because of the above 3 rewritecond's, this won't break poorly written admin scripts
RewriteRule .* - [S=1]

RewriteCond %{HTTPS} =on [OR]
RewriteCond %{HTTP_HOST} !^www\.askapache\.com$ [NC]
RewriteRule .* http://www.askapache.com%{REQUEST_URI} [R=301,L]

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /(wp-admin/.*|wp-login\.php.*)\ HTTP/ [NC]
RewriteCond %{HTTPS} !=on
RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

30x Faster Cache and Site Speed with TMPFS

NOT a typo.. 30x is measurable, well-documented, and easily tested. This is what open-source is about. I haven’t had time to post much the past year, I'm always working! So I wanted to make up for that by publishing an article on a topic that would blow your mind and be something that you could actually start using and really get some benefit out of it. This is one of those articles that the majority of web hosting companies would love to see in paperback, so they could burn it.

Advanced WordPress wp-config.php Tweaks

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..
