3 Ways to Serve PDF Files using Htaccess Cookies, Headers, Rewrites

Post by AskApache Aug 20, 20117 comments

FYI, using the Mod_Rewrite Variables Cheatsheet makes this example, and all advanced .htaccess code easier to understand. This demo lets you set a cookie with 1 of 3 values, then you just request the pdf file with a normal link click and get 1 of 3 different responses. This is accomplished with a nice bit of .htaccess code.

HOWTO: Uninstall CPANEL over SSH

Post by AskApache Jul 04, 20113 comments

The following is just a quick reference of some of the commands I used to successfully uninstall cpanel. This is for advanced users of the shell. If you aren't that advanced and you run a single one of these commands without fully understanding it, you will probably kill your server, probably lose everything on it permanently, probably not have a website or email for weeks.. So backup all your data FIRST. Also, if you aren't 100% sure you won't run into problems, you should contact your hosts technical support - but be prepared for some MAJOR negativity.. cpanel makes things very easy for hosts, you are just a drop in their bucket.

Wow!

You sure gotta bigger set that *I* do. . . . - for real! I've been known to do some abysmally stupid things in my day - and actually had them work the way I wanted them to! - but this takes the titanium, gadolinium, rhodium alloy cake!

Me, I'd try something like that and find out later that the fire-trucks showed up right after I hit the "Enter" key. It's a REALLY interesting post, and a real eye-opener - especially for someone who is relatively new to the whole web-hosting-service paradigm. I know, no guts, no glory - but THIS is WAY over the top! I'm reading this and thinking "Why not just put a couple of sticks of dynamite under the thing?"

Seriously now, this was an excellent read - and for someone who is just now looking into the whole web-hosting paradigm, it's a real eye-opener. Though I think I'll just tiptoe past this REAL QUIETLY for now. . . . (laughing!)

AskApache Password Protection 4.7 Update in 2 Weeks

Post by AskApache Nov 09, 20101 comment

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.

Adding YouTube Videos To Website, 4 Methods

Post by AskApache Oct 30, 20105 comments

This is the advanced example. It uses the jw flv player to create a flash proxy. This basically lets me control the youtube video as if it were a local .f4v file. With this method I can specify any options, autostart, volume, playlists, etc.. But it's rather complex so lets start with 3 other methods to embed YouTube video.

Advanced Windows Batch File Scripting

Post by AskApache Sep 03, 20107 comments

If for some reason you need to use windows .bat batch file scripting to do some task, or you just want to learn the most universal batch programming language on Windows machines, you lucked out and found the AskApache example. My expertise is the shell, in this article the shell is Windows cmd.exe. It has some pretty advanced windows shell usage, including pipes and redirection, but it's the modular linux-like coding approach that earns this script it's "advanced" title.

:SETPROMPT
set PROMPT=$_[%USERNAME%@%USERDOMAIN%]$S[$P]$_$M$G && EXIT /B

My favorite tool (and I've tried sooo many) for editing most Windows files and especially .bat files is the free and open-source Notepad++. Set that up and you will have a color-syntax-highlighted editor for Batch Scripting that works very very well.

I am almost ready to publish the final tutorial on using ssh tunnels from a truecrypt partition on a Windows machine. Of course I choose to go way overboard in my research and the tutorial is full of some pretty awesome windows tricks.. I will come back to this post soon and post all the other advanced tools I use for debugging windows, for now though you MUST know how to debug the kernel and use these basic debugging tools.

Crazy POWERFUL Bash Prompt

Post by AskApache May 25, 201011 comments

This amazing bash linux prompt does more than meets the eye. If you want to know how to become really good with technology, linux is the secret sauce behind the AskApache articles. Open Source is elixir of the web. Thanks to everyone who helped me for the past 20 years. I use linux/bsd because homey don't play, so this is geared to be as productive a prompt as I can make it.

Don't have much time.. or just don't care? Not a problem, here are the 3 lines to copy and paste - you can just paste them right in your shell to test it, or add to a startup script.

export AA_P="export PVE=\"\\033[m\\033[38;5;2m\"\$(( \`sed -n \"s/MemFree:[\\t ]\\+\\([0-9]\\+\\) kB/\\1/p\" /proc/meminfo\` / 1024 ))\"\\033[38;5;22m/\"\$((\`sed -n \"s/MemTotal:[\\t ]\\+\\([0-9]\\+\\) kB/\\1/p\" /proc/meminfo\`/ 1024 ))MB\"\\t\\033[m\\033[38;5;55m\$(< /proc/loadavg)\\033[m\";echo -en \"\""

Actual Htaccess Files from My Server

Post by AskApache Apr 17, 20106 comments

#### 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

30x Faster Cache and Site Speed with TMPFS

Post by AskApache Mar 18, 20107 comments

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

Post by AskApache Mar 03, 20106 comments

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..

Custom bash_profile for Advanced Shell Users

Post by AskApache Nov 23, 200911 comments

Looking for some advanced uses for the shell? Here is some of my best. The shell is where 70% of my work takes place, and I have at least one terminal open almost 100% of the time, for viewing tailing color-coded logs, and of course for the SSH Tunnels that I use to route various networking through, like my email. So I decided that to standardize and create a bash_profile containing the most time-saving and helpful functions that I could use on all the various hosting environments would really be some sweet sugar, so here is my constant Work-in-progress.

It works for all shells I encounter, including BackTrack, Debian, Knoppix, Arch Linux, etc. Also works for many hosting environments I use including DreamHost, HostGator, WiredTree, and pretty much any linux VPS.

I also rely on this heavily from within shell scripts I write to access all the functions and stuff in this .bash_profile, and to do that I just do like:

#!/bin/bash
 
source ~/.bash_profile &>/dev/nulll
 
pm "PM is a function to output nice messages with color"
yn "Are you enjoying the shell" && pm "Thats great!" || pm "Perhaps you're better suited for DOS"
yn "Show Calendar" && aa_calendar
yn "Show Fortune" && aa_fortune
