Simple SSL Redirects is a WordPress plugin designed to enhance the security of websites by enforcing SSL connections. It addresses the issue of accessing sites via both SSL (HTTPS) and non-SSL (HTTP) URLs, which can compromise security and affect SEO due to duplicate content concerns. The plugin employs 301 redirects to seamlessly direct users and search engines to the secure version of a site, ensuring all traffic is encrypted.

The plugin offers two primary methods for implementing these redirects. Firstly, it can intercept WordPress pages at the header level, issuing a 301 redirect for any non-HTTPS requests. Secondly, it allows users to add mod_rewrite rules in the .htaccess file for a more comprehensive redirection strategy. Additionally, Simple SSL Redirects can set HSTS headers and unify hostname access, addressing issues related to www and non-www URL variations.
