Apache Rewrite not rewriting as expected

  • 772

I'm trying to use mod_rewrite to redirect users to the HTTPS equivalent URL unless the URL is for my Jenkins CI server. Here is the rule I have in my default site config (my Jenkins and other sites have their own respective VirtualHost entries:

<VirtualHost _default_:80>
    ServerAdmin [email protected]
    RewriteEngine on
    ReWriteCond %{SERVER_PORT} !^443$
    ReWriteCond %{REQUEST_URI} !^.+/jenkins/(.*)$
    RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R,L]
</VirtualHost>

Any help would be greatly appreciated.

Edit: As requested, here is the output from apache2ctl -S:

VirtualHost configuration:
wildcard NameVirtualHosts and _default_ servers:
*:443                  is a NameVirtualHost
         default server ip-10-72-226-167.ec2.internal (/etc/apache2/sites-enabled/default-ssl:2)
         port 443 namevhost ip-10-72-226-167.ec2.internal (/etc/apache2/sites-enabled/default-ssl:2)
         port 443 namevhost qa.example.com (/etc/apache2/sites-enabled/example-ssl:2)
*:80                   is a NameVirtualHost
         default server ip-10-72-226-167.ec2.internal (/etc/apache2/sites-enabled/000-default:1)
         port 80 namevhost ip-10-72-226-167.ec2.internal (/etc/apache2/sites-enabled/000-default:1)
         port 80 namevhost qa.example.com (/etc/apache2/sites-enabled/jenkins:1)
Syntax OK

What I am expecting is that when I browse to http://qa.example.com that I get re-directed to https://qa.example.com/, but if I browse to http://qa.example.com/jenkins/ then my Jenkins config kicks in. The latter works, but the former does not, i.e. browsing to http://qa.example.com/ does not re-direct me to https://qa.example.com/.

    Instead of putting those rules in the _default_ vhost, put them in the /etc/apache2/sites-enabled/jenkins vhost, so that it can work against requests that have been mapped to that name.

    Also - the expression on your second RewriteRule won't ever match /jenkins/, since it's requiring at least one character before the leading slash. Try this:

    ReWriteCond %{SERVER_PORT} !^443$
ReWriteCond %{REQUEST_URI} !^/jenkins/.*$
RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [R,L]
