Introduction to HTTP to HTTPS Redirect Issues
When you’re aiming to enhance the security of your website, redirecting traffic from HTTP to HTTPS is a crucial step. However, many webmasters encounter frustrating issues, especially when working with subdomains. One common problem emerges when requests to a subdomain like http://scan.example.com are redirected to https://example.com/scan instead of the desired https://scan.example.com. This can lead to a confusing experience for your users and is detrimental to your site's SEO.
In this guide, we will explore a straightforward solution to ensure that your HTTP to HTTPS redirects work seamlessly for subdomains. We'll break down exactly what needs to be done in your .htaccess file to achieve this.
Understanding the Problem
Subdomains and Directories: In the scenario shared by a user, the subdomain scan.example.com is pointed to a subdirectory that also shares a similar name. When visiting the HTTP version, the redirecting server unintentionally appends the subdirectory path to the main domain, leading users to https://example.com/scan.
Redirecting Behavior: The mistake often arises from how rewriting rules are created in the .htaccess file. Backreferences like $1 may not be the best solution as they often retain unwanted subdirectory structures.
Solution: Adjust Your .htaccess Rules
To achieve the desired behavior, we need to adjust the existing rules in the .htaccess file. The rewritten rule should use the REQUEST_URI server variable instead of a backreference. Here's an updated code snippet to help you fix the issue:

Explanation of the Code Adjustments
RewriteCond %{HTTP_HOST} example.com [NC]: This condition checks if the requested host is example.com in a case-insensitive manner.
RewriteCond %{SERVER_PORT} 80: This line checks if the connection is made over HTTP (port 80).
RewriteCond %{HTTP_HOST} ^(?:www.)?(.+ ?).?$ [NC]: This condition captures any subdomain (including scan) while ignoring www, allowing preserved subdomains in redirects.
RewriteRule ^ https://%1%{REQUEST_URI} [R=301,L]: Here we redirect to https://<subdomain>%{REQUEST_URI}, ensuring that the subdomain can correctly capture each redirect without adding any unintended directory paths.
Conclusion: Managing Your HTTP to HTTPS Redirects
By making these adjustments to your .htaccess file, you will solve the redirect problem from http://scan.example.com to https://scan.example.com. This not only enhances user experience but also helps maintain the integrity of your website's structure and SEO performance.

Happy redirecting, and may your transition from HTTP to HTTPS be smooth sailing!
