.htaccess将www和非www映射到文件夹并维护www

Question

I am no .htaccess expert and extremely rarely use it. I went through several solutions on Net and SO but no luck still. So I have one IP says 1.2.3.4 that has sub folder of my wordpress application says ABC in the /var/www/html/ . DNS has been setup so that www.mydomain.com and mydomain.com point to IP 1.2.3.4 .

I have my content in .htaccess file as below and it only supports mydomain.com . The content is displayed as expected except when I put www.mydomain.com it displays Linux home page.

RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} ^mydomain\.com$
RewriteCond %{REQUEST_URI} !^/ABC/
RewriteRule (.*) /ABC/$1

When I put www.mydomain.com the browser automatically change the URL to mydomain.com .

Apart from that, I would also like to have all domain with www . Means request from mydomain.com will be displayed as www.mydomain.com . Later I will just put www.mydomain.com in the URL config of my wordpress. Some helps are appreciated.

Switch back to your old .htaccess code. I got it more clear after your last update. You have wordpress files in "public_html/ABC" but need your website url as www.example.com. Let me explain step by step.

1. Paste your old code in .htaccess.
2. copy (do not move) the index.php and .htaccess file from the /ABC folder to the "public_html" of your site.
3. Find one rule in "public_html/index.php" as "require( dirname( FILE ) . '/wp-blog-header.php' );" and replace it with "require( dirname( FILE ) . '/ABC/wp-blog-header.php' );" (do not edit the index.php file in the folder /ABC!!)
4. change ONLY the "Site Address (URL)" in the general settings (Settings -> General) to " http://www.example.com ".

So finally I managed to get what I want to be working with below solution. Hopefully this will help somebody out there:

RewriteEngine on
RewriteBase /

# Whatever request coming to the server, add www to it
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

# Map the www URL to the subfolder in root directory    
RewriteCond %{HTTP_HOST} www\.myurl\.com$
RewriteCond %{REQUEST_URI} !^/thefolder/
RewriteRule (.*) /thefolder/$1

For Wordpress part, I have put codes in wp-config.php as below:

define('WP_HOME','http://www.myurl.com');
define('WP_SITEURL','http://www.myurl.com');

Thank you. Cheers.

UPDATE I have just realized that after the changes above, I could not able to login to my WP admin page. This is due to wrong redirect. It looks something like http://www.myurl.com/wp-login.php?redirect_to=http%3A%2F%2Fwww.myurl.com%2Fthefolder%2Fwp-admin%2F&reauth=1

When I remove the thefolder from URL it redirects to expected page. Can somebody advice on this?
