READ ME FIRST
As a configuration file, .htaccess is very powerful. Even the slightest syntax error (like a missing space) can result in your content not displaying correctly or at all.
Since .htaccess is a hidden system file, please make sure your FTP client is configured to show hidden files. This is usually an option in the program’s preferences/options.
1. Create an empty text file using a text editor such as notepad, and save it as htaccess.txt.
The reason you should save the file as htaccess.txt is because many operating systems and FTP applications are unable to read or view .htaccess files by default. Once uploaded to the server you can rename the file to .htaccess.
2. Edit the contents of the file. Check the following examples:
Point an entire site to a different URL, such as domain.net redirected to domain.com:
# This allows you to redirect your entire website to any other domain
Redirect 301 / http://example.com/
Redirect index.html to a specific subfolder:
# This allows you to redirect index.html to a specific subfolder
Redirect /index.html http://example.com/newdirectory/
Redirect an old file to a new file path:
# Redirect old file path to new file path
Redirect /olddirectory/oldfile.html http://example.com/newdirectory/newfile.html
Redirect to a specific index page:
# Provide Specific Index Page (Set the default handler)
3. Upload this file and re-name it to .htaccess.
If using a text editor, be sure to save the file as plain text.
Paths to where you should save this file can be found in this article: System paths.
The definitive guide on Apache directives that can be used in .htaccess files can be found here: http://httpd.apache.org/docs/mod/core.html.
More powerful URL changes with mod_rewrite
If you need to make complex changes to the way your URL displays, you should visit Using .htaccess rewrite rules. You can do things like add “www” to the beginning of your URL, redirect all requests to a subfolder but keep the rest of the URL, etc.
