The purpose of this plugin is to facilitate deployment of subdomain links to 
landing pages on a WordPress website. The plugin automatically maps subdomains 
to page and post permalinks based on the post_name field in the database. 
There are no administrative settings.
This plugin DOES NOT edit DNS zone files. Subdomain DNS records themselves 
either need to be set up individually or as a wildcard record in the DNS zone 
file to map to the website directory. Once the request reaches the WordPress 
system, the plugin will automatically check to see if the subdomain matches a 
page or post name. If so, the WordPress query is edited to get that page/post 
at its permalink. The WordPress siteurl is excluded, as is the naked 
second-level domain.
Example mappings:
URL → Mapping 
http://example.com → default homepage (no remapping) 
http://www.example.com → default homepage (no remapping) 
http://test-page.example.com → example.com/test-page/ 
http://mypost.example.com → example.com/mypost/

Automatic Subdomains

Automatically maps subdomains to page and post permalinks based on post slug.

Add or Remove Www seeks to solve a common problem: preventing redirects from a www- version to a non-www version of a site — or vice-versa.
It’s common that you’ll create a content link or include an image, linking to http://YourSiteNameHereForExample.com/imageExample.jpg — but your server then redirects that to http://www.YourSiteNameHereForExample.com/imageExample.jpg . That adds in an extra server request and delay to the user.
One solution is to go through every image and link, one by one, and make sure they’re all consistent. Another solution is… to use our plugin.
We plan on adding more options to be edited — if you have any other suggestions, please let us know! You can contact us via http://www.wpsos.io/wordpress-plugin-add-or-remove-www/
