问题
I am using a single domain certificate (only on the www. subdomain) and want to have all users using this.
Currently i have the following in my htaccess file:
## force HTTPS and www. if any of them are not already present
RewriteCond %{HTTP_HOST} (?!^www\.)^(.+)$ [OR]
RewriteCond %{HTTPS} off
RewriteRule ^ https://www.%1%{REQUEST_URI} [R=301,L]
But the problem is, that this seems to lead to two separate redirects:
http://domain.com -> https://domain.com -> https://www.domain.com
This means 3 RTTs for the user until he reaches the correct page. In addition only the second redirect seems to be permanent, the first one (http to https) seems to be temporary,
Is there any solution which directly sends requests of from http to https+www?
Many thanks in advance!
回答1:
There's only one redirect. The target is https://www.%1. There is no redirect to http://www.%1 and no redirect to https://%1. Only https://www.%1.
No idea how you arrived at the conclusion that this rule caused 2 different redirects. Is this what your access logs are saying? Or the browser's network console?
