301 redirect http links to corresponding https links

Question

We are using the SSL securing the whole site now. At the admin end, unsecure and secure URL are all in the form of https.

Now the issue we are facing right now is, for example, the link "http://www.example.com/abc" is 301-redirected to "https://www.example.com". The correct way is to redirect to "https ://www.example.com/abc

Anyone can share the idea the correct way to do it?

Thanks!

Answer 1

Based on the hints by Simon, here is what I have:

1) Make sure "Auto-redirect to Base URL = No". It was set to "yes", and causing the problem.

2) Put the below in the .htaccess:

RewriteCond %{HTTPS} off
 RewriteCond %{HTTP_HOST} !^www\.(.*)$ [NC]
 RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

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

 RewriteCond %{SERVER_PORT} !^443$
 RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

It works for me, at least for now.

Answer 2

This will redirect http to https while preserving the querystring:

RewriteCond %{HTTP_HOST} www\.yourdomain\.com [NC]
RewriteRule ^(.*)$ https://www.yourdomain.com/$1 

Answer 3

Try this in your .htaccess file:

############################################
## enables the usage of %{ENV:proto} as the protocol (http vs https) in the rewrite rules
    RewriteCond %{HTTPS} =on
    RewriteRule ^(.*)$ - [env=proto:https]
    RewriteCond %{HTTPS} !=on
    RewriteRule ^(.*)$ - [env=proto:http]

############################################
## redirect from non-www to www
    RewriteCond %{HTTP_HOST} !^www\. [NC]
    RewriteRule ^ %{ENV:proto}://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

It is quite generic and works for me. It also ensures that www. is always used. It is based on this StackOverflow answer.
