What is .htaccess

.htaccess, where ht is hypertext and access is access - is a configuration file used by the Apache webserver. This file can specify a number of server settings such as enable/disable additional functionality and features that Apache has to offer. For example authorization and authentication, changing URL addresses, managing cache, changing the look of the 404, 500 error pages and so on.

It applies only to the given directory in which the file is located and its subdirectories. Like any configuration file, .htaccess is a text ASCII file and can be edited with any text editor. The .htaccess file must begin with the period character.

.htaccess files are used in almost all Apache web servers worldwide. There are a number of settings that cannot be done any other way than with .htaccess, and there are some that .htaccess makes much easier. Most hosting providers including BlueVPS support .htaccess.

The .htaccess files act as a subset of the server's global configuration file (such as httpd.conf) for the directory in which they reside or any subdirectories.

Let’s proceed then.

From http to https

To configure redirection, in the directory of your site, add to the beginning of the file .htaccess (if this file does not exist, then create, note the file starts with a dot), the following lines:

RewriteEngine On

RewriteCond %{HTTPS} off

RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Alternative:

RewriteEngine On

RewriteCond %{HTTP:X-HTTPS} !1

RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

From https to http

Go to your .htaccess file and these lines:

RewriteEngine on

RewriteCond %{HTTPS} on

RewriteRule ^.*$ http://%{SERVER_NAME}%{REQUEST_URI}

Redirect from one page to another

Redirect 301 /testpage1/ http://abcdtestdomain.xyz/testpage2/
