.htaccess redirect http to https

I have an old url (www1.test.net) and I would like to redirect it to https://www1.test.net
I have implemented and installed our SSL certificate on my site.
This is my old file .htaccess:

RewriteEngine On
RewriteRule !\.(js|gif|jpg|png|css|txt)$ public/index.php [L]
RewriteCond %{REQUEST_URI} !^/public/
RewriteRule ^(.*)$ public/$1 [L]

How can I configure my .htaccess file so that url auto redirect to https?
Thanks!

I use the following to successfully redirect all pages of my domain from http to https:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

Note this will redirect using the 301 'permanently moved' redirect, which will help transfer your SEO rankings.

To redirect using the 302 'temporarily moved' change [R=302,L]

Update 2016

As this answer receives some attention, I want to hint to a more recommended way on doing this using Virtual Hosts: Apache: Redirect SSL

<VirtualHost *:80>
   ServerName mysite.example.com
   Redirect permanent / https://mysite.example.com/
</VirtualHost>

<VirtualHost _default_:443>
   ServerName mysite.example.com
   DocumentRoot /usr/local/apache2/htdocs
   SSLEngine On
# etc...
</VirtualHost>

Old answer, hacky thing given that your ssl-port is not set to 80, this will work:

RewriteEngine on

# force ssl
RewriteCond     %{SERVER_PORT} ^80$
RewriteRule     ^(.*)$ https://%{SERVER_NAME}%{REQUEST_URI} [L,R]

Note that this should be your first rewrite rule.

Edit: This code does the following. The RewriteCond(ition) checks wether the ServerPort of the request is 80 (which is the default http-port, if you specified another port, you would have to adjust the condition to it). If so, we match the whole url (.*) and redirect it to a https-url. %{SERVER_NAME} may be replaced with a specific url, but this way you don't have to alter the code for other projects. %{REQUEST_URI} is the portion of the url after the TLD (top-level-domain), so you will be redirected to where you came from, but as https.

This is the best for www and for HTTPS, for proxy and no proxy users.

RewriteEngine On

### WWW & HTTPS

# ensure www.
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# ensure https
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

### WWW & HTTPS

I force the https with following code:

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

Add this code at the end of your .htaccess file

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

In cases where the HTTPS/SSL connection is ended at the load balancer and all traffic is sent to instances on port 80, the following rule works to redirect non-secure traffic.

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

Ensure the mod_rewrite module is loaded.

Searching for the best way to redirect, i've found this (coming from html5boilerplate) :

# ----------------------------------------------------------------------
# | HTTP Strict Transport Security (HSTS)                              |
# ----------------------------------------------------------------------

# Force client-side SSL redirection.
#
# If a user types `example.com` in their browser, even if the server
# redirects them to the secure version of the website, that still leaves
# a window of opportunity (the initial HTTP connection) for an attacker
# to downgrade or redirect the request.
#
# The following header ensures that browser will ONLY connect to your
# server via HTTPS, regardless of what the users type in the browser's
# address bar.
#
# (!) Remove the `includeSubDomains` optional directive if the website's
# subdomains are not using HTTPS.
#
# http://www.html5rocks.com/en/tutorials/security/transport-layer-security/
# https://tools.ietf.org/html/draft-ietf-websec-strict-transport-sec-14#section-6.1
# http://blogs.msdn.com/b/ieinternals/archive/2014/08/18/hsts-strict-transport-security-attacks-mitigations-deployment-https.aspx

Header set Strict-Transport-Security "max-age=16070400; includeSubDomains"

Maybe it will help someone in 2017 ! :)

Insert this code in your .htaccess file. And it should work

RewriteCond %{HTTP_HOST} yourDomainName\.com [NC]
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://yourDomainName.com/$1 [R,L]

This makes sure that redirects work for all combinations of intransparent proxies.

This includes the case client <http> proxy <https> webserver.

# behind proxy
RewriteCond %{HTTP:X-FORWARDED-PROTO} ^http$
RewriteRule (.*) https://%{HTTP_HOST}/$1 [R=301,L]

# plain
RewriteCond %{HTTP:X-FORWARDED-PROTO} ^$
RewriteCond %{REQUEST_SCHEME} ^http$ [NC,OR]
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}/$1 [R=301,L]

Use the following code or you can read more in detail on this topic. How to redirect HTTP to HTTPS Using .htaccess?

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

I had a problem with redirection also. I tried everything that was proposed on Stackoverflow. The one case I found by myself is:

RewriteEngine on
RewriteBase /
RewriteCond %{HTTP:SSL} !=1 [NC]
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

Adding the following to the top of the .htaccess

RewriteEngine On
RewriteCond %{ENV:HTTPS} !=on
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R,L]

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

This is what ended up working for me

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
</IfModule>

Forcing HTTPS with the .htaccess File

==> Redirect All Web Traffic :-

To force all web traffic to use HTTPS, insert the following lines of code in the .htaccess file in your website’s root folder.

RewriteEngine On 
RewriteCond %{HTTPS} !on
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

==> Redirect Only Specified Domain :-

To force a specific domain to use HTTPS, use the following lines of code in the .htaccess file in your website’s root folder:

RewriteCond %{REQUEST_URI} !^/[0-9]+\..+\.cpaneldcv$
RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$
RewriteEngine On 
RewriteCond %{HTTP_HOST} ^example\.com [NC]
RewriteCond %{SERVER_PORT} 80 
RewriteRule ^(.*)$ https://www.example.com/$1 [R=301,L]

If this doesn’t work, try removing the first two lines.

RewriteEngine On
RewriteCond %{HTTP_HOST} ^example\.com [NC]
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.example.com/$1 [R=301,L]

> Make sure to replace example.com with the domain name you’re trying > force to https. Additionally, you need to replace www.example.com with > your actual domain name.

==> Redirect Specified Folder :-

If you want to force SSL on a specific folder, insert the code below into a .htaccess file placed in that specific folder:

RewriteCond %{REQUEST_URI} !^/[0-9]+\..+\.cpaneldcv$
RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$
RewriteEngine On 
RewriteCond %{SERVER_PORT} 80 
RewriteCond %{REQUEST_URI} folder
RewriteRule ^(.*)$ https://www.example.com/folder/$1 [R=301,L]

> Make sure you change the folder reference to the actual folder name. > Then be sure to replace www.example.com/folder with your actual domain > name and folder you want to force the SSL on.

Replace your domain with domainname.com , it's working with me .

RewriteEngine On
RewriteCond %{HTTP_HOST} ^domainname\.com [NC]
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.domainname.com/$1 [R,L]
