How to use mod_rewrite in .htaccess - Simple tutorial

Here is my little experience on using mod_rewrite and .htaccess:

Environment: Ubuntu 6.10 - Apache 2.0.55 + PHP5

To start using mod_rewrite:

1. In your httpd.conf (In my case: apache2.conf), you will notice a line

AccessFileName .htaccess

Please ensure this line exist in your httpd.conf anywhere.

2. Still in httpd.conf: Find out your web root directory defined in <Directory> tags. This is the directory where you would place your .htaccess file in. Once your .htaccess file, which will be made later, is put in this directory, it will take effect immediately, without restart/reload your apache2.

Please find out the following line:

AllowOverride None

and change it to

AllowOverride All

This make the text(directive) which is defined in .htaccess work. AllowOverride means "What text(directive) is allowed to be override by .htaccess?". So, if AllowOverride is "None", it means that .htaccess cannot override anything = useless.

3. At anywhere in your httpd.conf, put the following lines:

RewriteLog /path/to/your/log/file/≶your_log_file_name>
RewriteLogLevel 2

It's ok even if you haven't create this file yet, it will be created automatically.
Log level is 2 here, If you want to see simple log, please enter 1. If you want detail log, enter a higher number....

4. Create a .htaccess file in your web root:

vi .htaccess

and enter the following text

RewriteEngine On
RewriteRule ^info\.php$ http://www.google.com

The first line defined that the mod_rewrite engine should be turned on. This line is only required once per .htaccess file.

The second line defined the rule set. Preceding with "RewriteRule <From> <To>", you can enter regular expression here to "rewrite" your URL. In this example, if you enter http://localhost/info.php, you will be redirected to http://www.google.com

To see the details on how to use mod_write and why using this, please refer to the following website:

TCPDF How to show/display Chinese Character?

Thanks to this article (in Simplified Chinese, updated new link), there is a way to embed a TTF that can display Chinese (Traditional and Simplify, and possibly Japanese). Environment:  TCPDF 6.0.020 PHP 5.3.8 Windows 7 The problem: If you follow this post that said: using cid0cs or cid0ct to display Chinese, it can display the character correctly, only to the extend that user installed a correct font package.  However, chances are other users who didn't install that package cannot view that PDF since there are several packages and versions of PDF viewer (mainly Adobe).  And even worse: even if user installed certain CJK font package, the PDF still not displayed correctly (show empty page). And according to the official TCPDF documentation about font : The fonts that could be not embedded are only the standard core fonts and CID-0 fonts . The solution: Again, thanks to the post above (in simplified Chinese), now developer can use a font that: Can disp...

How to fix fancy box/Easy Fancybox scroll not work in mobile

Hi The Problem: If you are working on EasyFancybox or just normal fancybox JS , and you have this problem: In your iOS device when a popup is opened, if the page is too wide and your pop up cannot show all, when user taps and drag the screen, the background will be dragged instead of the pop-up content. To fix, add this in your CSS: -webkit-overflow-scrolling: touch !important; So which element should you apply it to? In Easy Fancybox, you will see these 2 lines: <div id="fancybox-content"........>         <iframe id="fancybox-frame" name............... Apply to fancybox-content, not fancybox-frame So in your CSS, it should be: #fancybox-content{         overflow: scroll !important;         -webkit-overflow-scrolling: touch !important; } It works for me, and I hope it helps someone also.

Wordpress Load balancing: 2 web servers 1 MySQL without any Cloud services

Image
This is the exact config that I need to configure a load balancing without other cloud services like Amazon, rackspace or GoGrid, completely customized. I put my question on stackoverflow.com but no luck, so I put it on Quora.com and immediately I got response: My Notes: The load balancer is done by my colleagues so I am not sure what is the config of it.  But one thing to note: Your LB should enable "session stickiness" so that the session will follow visitor.  By the way, I am using Round-robins. Session: Actually I did not use session, but it seems that other plugins (like WPML) will use it.  If I use Apache load balancer, when I go to wp-admin through load balancing IP, I will not able to login, given the username and password is the same.  I will be redirected to login page.  So ask your load balancer providers or check your load balancer config and see how to manage the "Session Stickiness" issue. Shared folder: your wp-content/uploads folder...
