.htaccess重定向到https和www。 如果启用

Question

I want to configure my .htaccess file in a manner where it will do these two things:

• ALWAYS make sure www. is appended (even for subdomains like so: www.sub.example.com ).
• OPTIONALLY add https:// if it is enabled.

I preferably (if possible) want to do this in one rewrite rule, currently I have this:

RewriteEngine On

RewriteCond %{HTTPS} !=on [OR]
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
RewriteRule ^ https://www.%1%{REQUEST_URI} [L,NE,R=301]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule ^(.+)$ index.php?url=$1 [QSA,L]

So how do I make the s of https:// optional in the same rewrite?

Answer 1

You can use the following Rule to redirect https , non-https and non-www requests to www with a single redirect.

RewriteEngine on


RewriteCond %{HTTP_HOST} !^www\.
RewriteCond %{HTTPS}s on(s)|offs()
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [NE,L,R]

This is doing a 302 Temporary redirect. If you want a 301 permanent redirect, change the R flag to R=301 .
