You can see them on the server with i.e. Phpinfo, or by dumping the $SERVER variable: 2) The reason the redirects weren't working (to fix the DirectorySlash issue) is because in addition to the RewriteRules listed above, your htaccess must include RewriteOptions AllowNoSlash.

Get Firefox, a free web browser backed by Mozilla, a non-profit dedicated to internet health and privacy. Available now on Windows, Mac, Linux, Android and iOS. X-Forwarded-For The X-Forwarded-For (XFF) header is a de-facto standard header for identifying the originating IP address of a client connecting to a web server through an HTTP proxy or a load balancer. When traffic is intercepted between clients and servers, server access logs contain the IP address of the proxy or load balancer only.

Further Information
- Virtual Hosts

To easily enable (and enforce) WordPress administration over SSL, there are two constants that you can define in your site’s wp-config.php file. It is not sufficient to define these constants in a plugin file; they must be defined in your wp-config.php file. You must also already have SSL configured on the server and a (virtual) host configured for the secure server before your site will work properly with these constants set to true.

Note: FORCE_SSL_LOGIN was deprecated in Version 4.0. Please use FORCE_SSL_ADMIN.

To Force SSL Logins and SSL Admin Access To Force SSL Logins and SSL Admin Access

The constant FORCE_SSL_ADMIN can be set to true in the wp-config.php file to force all logins and all admin sessions to happen over SSL.

Example Example

Using a Reverse Proxy Using a Reverse Proxy

If WordPress is hosted behind a reverse proxy that provides SSL, but is hosted itself without SSL, these options will initially send any requests into an infinite redirect loop. To avoid this, you may configure WordPress to recognize the HTTP_X_FORWARDED_PROTO header (assuming you have properly configured the reverse proxy to set that header).

Example Example

Further Information Further Information

The rest of this article serves as information in case you’re using an older version of WordPress (which ideally you shouldn’t!) or your SSL setup is somewhat different (ie. your SSL certificate is for a different domain).

Sometimes, you want your whole wp-admin to run over a secure connection using the https protocol. Conceptually, the procedure works like this:

Set up two virtual hosts with the same url (the blog url), one secure, the other not.
On the secure virtual host, set up a rewrite rule that shuttles all non-wp-admin traffic to the insecure site.
On the insecure virtual host, set up a rewrite rule that shuttles all traffic to wp-admin to the secure host.
Put in a filter (via a plugin) that filters the links in wp-admin so that once activated, administrative links are rewritten to use https and that edits cookies to work only over encrypted connections.

The following guide is for WordPress 1.5 and Apache running mod_rewrite, using rewrite rules in httpd.conf (as opposed to .htaccess files) but could easily be modified to fit other hosting scenarios.

Virtual Hosts Virtual Hosts

You need a (virtual) host configured for the secure server in addition to the non-secure site. In this example, the secure virtual host uses the same DocumentRoot as the insecure host. Hypothetically, you could use a host with a different name, such as wpadmin.mysite.com and link the document root to the wpadmin directory.

Please ask your ISP to set up a secure virtual host for you, or if you have administrative access set up your own. Note that you cannot use name based virtual hosting to identify different SSL servers.

Rewrite Rules For The Insecure Host Rewrite Rules For The Insecure Host

In the .htaccess or virtual host stanza in httpd.conf for your insecure host, add this rewrite rule to automatically go to the secure host when you browse to http://mysite.com/wp-admin/ or http://mysite.com/wp-login.php

This should go above the main wordpress rewrite block.

If you are using permalink rewrite rules, this line must come before RewriteRule ^.*$ - [S=40].

An important idea in this block is using THE_REQUEST, which ensures only actual http requests are rewritten and not local direct file requests, like an include or fopen.

Rewrite Rules For Secure Host (Optional) Rewrite Rules For Secure Host (Optional)

These rewrite rules are optional. They disable access to the public site over a secure connection. If you wish to remain logged in to the public portion of your site using the plugin below, you must not add these rules, as the plugin disables the cookie over unencrypted connections.

The secure virtual host should have two rewrite rules in an .htaccess file or in the virtual host declaration (see Using Permalinks for more on rewriting):

The first rule excludes the wp-admin directory from the next rule, which shuffles traffic to the secure site over to the insecure site, to keep things nice and seamless for your audience.

Setting WordPress URI Setting WordPress URI

For some plugins to work, and for other reasons, you may wish to set your WordPress URI in options to reflect the https protocol by making this setting https://mysite.com. Your blog address should not change.

Example Config Stanzas Example Config Stanzas

NOTE: The below config is not 100% compatible with WordPress 2.8+, WordPress 2.8 uses some files from the wp-includes folder. The redirection that the first set of Rewrite rules introduces may cause security warnings for some users. See https://core.trac.wordpress.org/ticket/10079 for more information.

Rewrite for Login and Registration Rewrite for Login and Registration

It is probably a good idea to utilize SSL for user logins and registrations. Consider the following substitute RewriteRules.

Insecure

Rewrite for sites running on port 443 or port 80 Rewrite for sites running on port 443 or port 80

Summary Summary

This method does not fix some inherent security risks in WordPress, nor does it protect you against man-in-the-middle attacks or other risks that can cripple secure connections.

However, this should make it much harder for a malicious person to steal your cookies and/or authentication headers and use them to impersonate you and gain access to wp-admin. It also obfuscates the ability to sniff your content, which could be important for legal blogs which may have drafts of documents that need strict protection.

Verification Verification

On the author’s server, logs indicate that both GET and POST requests are over SSL and that all traffic to wp-admin on the insecure host is being shuttled over to the secure host.

Sample POST log line:

More testing, preferably with a packet sniffer and some hardcore network analysis tools, would help to confirm.
