More instructions (3) How to redirect HTTP to HTTPS by .htaccess or PHP Script

The most common problem after the SSL Certificate installed. When you access to website by www.yourdomain.com or yourdomain.com (without typing https://) on the web browser's address Bar does not show the Padlock (green key) This is because of a typical web browser will call a web page via a standard protocol http // (Port 80). It is therefore necessary to set the Redirecct to force the web browser to fetch web pages via Protocol https:// (Port 443) instead. Use the configuration method in the file .htaccess (For Web Server Apache or Nginx) or put the script in the PHP file.

Redirecct with .htaccesse (Linux) Create a blank text file with a text editor such as Notepad and save as htaccess.txt. Then copy 5 lines command below and plaste into the htaccess.txt file, Upload the htaccess.txt file to folder /public_html. Then rename the file to .htaccess.

Warning: If you have file .htaccess already, Edit the old file and copying the below command from <IfModule mod_rewrite.c> to </IfModule> Then paste in .htaccess file.

Redirecct with PHP Script Open a .php file with a Text Editor such as Notepad. Copy the command below. Placed at the top of the file. ( Place after command <? php ) This may not be convenient because you may must edit all .php files, but it is best for set redirect only for specific pages like index.php.

Redirecct with web.config (Windows & Plesk) Create a blank text file with a text editor such as Notepad and save as web.config.txt. Then copy 5 lines command below and plaste into the web.config.txt file, Upload the web.config.txt to folder /httpdocs. Then rename the file to web.config

Warning: If you have file web.config already, Edit the old file and copying the below command from <system.webServer> to </system.webServer> Then paste in web.config file.
