For WordPress files like wp- login.php, that’s specifically how the login screen is generated. once bestowed with a fairly permalink like intylestyle.co.uk/2012/web-design agency-london/.htaccess, the web server simply must load the most loop of WordPress so the core code will parse the URL and switch it into a info query that finds a post with the title Haddonfield within the class Travel. unlike a static web site wherever you’d have created a file thereupon name, WordPress stores its content in a very database — solely some files are loaded directly.
