Saving requests over SSL connection?

Question

PHP

If the site worked on http and then switched to https, but some requests go to the old address on http (old links, forms from other sites, requests to the API), is it possible to redirect all this to https without damage and give the correct answer so that for external users nothing has changed?

Answer 1

Can. Add a redirect from http to https.
In the case of apache, this can be done by adding the following lines to the virtualhost:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
