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.

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.

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..

I am often logged in to my servers via SSH, and I need to download a file like a WordPress plugin. I've noticed many sites now employ a means of blocking robots like wget from accessing their files. Most of the time they use .htaccess to do this. So a permanent workaround has wget mimick a normal browser.
