.htaccess redirect url example

If I want to direct the non-www version of whhsupport.com to the www version I would place the following code into my .htaccess file:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^whhsupport.com
RewriteRule (.*) http://www.whhsupport.com/$1 [R=301,L]

Conversely, if I want to direct the www version of whhsupport.com to the non-www version, I would enter the following code into my .htaccess file:

RewriteEngine on
Options +FollowSymLinks
RewriteCond %{HTTP_HOST} ^www\.whhsupport\.com$ [NC]
RewriteRule ^(.*)$ http://whhsupport.com/$1 [R=301,L]

1) short_open_tag = Off

 This will not allow the shout tags like , if this is set off

2) max_execution_time = 30

Maximum execution time of th script, in seconds

3) error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT

This shows all errors, except coding standards warnings. Some more examples for

error_reporting setting:

- Show all errors, except for notices and coding standards warnings

error_reporting = E_ALL & ~E_NOTICE

error_reporting= E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR

4) display_errors = On

Print errors (as a part of the output). For production web sites turn this feature off, and use error logging instead (see below). Keeping display_errors enabled on a production web site may reveal security information to end users, such as file paths on your Web server, your database schema or other information.

5) log_errors = On

Create Log of errors into a log file (server-specific log, or error_log). You should use error logging in place of error displaying on production web sites.

6) register_globals = Off

You should do your best to write your scripts so that they do not require register_globals to be on.

Using form variables as globals can easily lead to possible security problems, if the code is not very well. Making register_global  on can make securitry hole.

This sets the maximum amount of memory in bytes that a script is allowed to allocate. This helps prevent poorly written scripts for eating up all available memory on a server.

This setting also affects file upload. To upload large files, this value must be larger than upload_max_filesize. If memory limit is set by your configure script, memory_limit also affects file uploading. Generally , memory_limit should be more than post_max_size .

9) file_uploads = On

Allow HTTP file uploads or not.

Maximum allowed size for uploaded files. Default is  2MB.
