Subject [Httpd Wiki] Update of "Recipes/RedirectSSL" by JohnCrown
Date Wed, 03 Jan 2007 23:57:07 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Httpd Wiki" for change notification.

The following page has been changed by JohnCrown:
http://wiki.apache.org/httpd/Recipes/RedirectSSL

------------------------------------------------------------------------------

+ 
  Let's say you want http://www.domain.com/secure/ to always be sent over SSL (I presume here
that both the normal and the SSL vhost have the same content). You could do this by linking
to the correct page from within your HTML pages... but there will always be some user who
will sneak by it that way.

  When using SSL, you will frequently have at least two virtual hosts: one on port 80 to serve
ordinary requests, and one on port 443 to serve SSL.  If you wish to redirect users from the
non-secure site to the SSL site, you can use an ordinary [http://httpd.apache.org/docs/trunk/mod/mod_alias.html#redirect
Redirect] directive inside the non-secure VirtualHost:

+ === Most Secure SSL Forcing Method '''(doesn't require mod_rewrite!)''' ===
+ 
+ This will check to make sure that the connection is using SSL, or it will fail. This works
regardless of if you are serving SSL on port 443, 80, 81, etc. This is the most secure setting
for SSL logins.
+ 
+ This also fixes having to type in the username and password twice by requiring the HTTP_HOST
to match the HTTP_HOST that your SSL certificate is set-up for, in the case above, the SSL
is for google.com not www.google.com
+ 
+ So if either of those 2 checks fail '''(!SSL or !correct domain)''' than the (403) ErrorDocument
directive issues a 302 Found, Location: https://google.com which forces the client to connect
to the correct location. 
+ 
+ {{{
+ [IfModule mod_ssl.c]

+ }}}
+

+ === Rewrite non-SSL requests to SSL '''(doesn't require mod_ssl!)''' ===
+ 
+ {{{
+ [IfModule !mod_rewrite.c]
+ RewriteCond %{HTTPS} !=on
+ RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [QSA,R=301,L]
+ [/IfModule]
+ }}}
+ 
+ ''NOTE'': The HTTPS variable is always present, even if mod_ssl isn’t loaded!
+ 
+ 
+ 
+ 
+ === Redirect everything served on port 80 to SSL ===
+ 
+ {{{
+ RewriteCond %{SERVER_PORT} ^80$
+ RewriteRule ^.*$ https://%{HTTP_HOST}%{REQUEST_URI} [QSA,R=301,L]
+ }}}
+ 
+ 
+ 
+ === Changing to SSL or non-SSL using relative URLs ===
+ 
+ {{{
+ RewriteRule ^/(.*):SSL$   https://%{SERVER_NAME}/$1 [QSA,R,L]
+ RewriteRule ^/(.*):NOSSL$ http://%{SERVER_NAME}/$1 [QSA,R,L]
+ }}}
+ This lets you use hyperlinks in your web document of the form
+ {{{
+ /document.html:SSL    --> https://google.com/document.html
+ /document.html:NOSSL  --> http://google.com/document.html
+ }}}
