Virtual Hosting, HTTP 302 to HTTPS?

Dear group,

I have two web applications (a,b) that are both reachable via subdomains:

a.example.com <http://a.example.com/>
b.example.com <http://b.example.com/>

For b.example.com <http://b.example.com/> exists a SSL certificate. 
a.example.com <http://a.example.com/> does not need SSL.
The HTTPS connector uses a a Java keystore with the certificate. 

I configured Apache Tomcat 8.0.20 with Virtual Hosting.

CATALINA_HOME/webapps_a
CATALINA_HOME/webapps_b

The server.xml has been adjusted.

<Engine name="Catalina" defaultHost="b">

 <Host name="a" appBase="webapps_a" unpackWARs="true" autoDeploy="true">
   ...
 </Host>

 <Host name="b" appBase="webapps_b" unpackWARs="true" autoDeploy="true">
   ...
 </Host>

</Engine>

Both web apps are deployed using ROOT.war. They get unpacked and there are no errors in the log files.

Here is my problem. b works fine, but I can't reach a.

curl -I http://a.example.com <http://a.example.com/>
HTTP/1.1 302 Found
Server: Apache-Coyote/1.1
Cache-Control: private 
Expires: Thu, 01 Jan 1970 01:00:00 CET
Location: https://a.example.com <https://a.example.com/>
Content-Length: 0
Date: Mon, 01 Feb 2016 13:52:32 GMT

curl -I http://b.example.com <http://b.example.com/>
HTTP/1.1 302 Found
Server: Apache-Coyote/1.1
Cache-Control: private 
Expires: Thu, 01 Jan 1970 01:00:00 CET
Location: https://b.example.com <https://b.example.com/>
Content-Length: 0
Date: Mon, 01 Feb 2016 13:52:54 GMT  

The redirect sets Location to https. I know this can't work because I have no
certificate for srv.grasmueck.de <http://srv.grasmueck.de/> nor do I need https.

And I see the web application `b` instead of `a` despite the error.

Do I need a Apache HTTPD fronted? 


Thanks for the support! I appreciate it.

Björn

Hi Jeff,

the web application with the certificate does have a security constraint in the web.xml.

<security-constraint>
        <web-resource-collection>
            <url-pattern>/index.xhtml</url-pattern>
        </web-resource-collection>
        <user-data-constraint>
            <transport-guarantee>CONFIDENTIAL</transport-guarantee>
        </user-data-constraint>
</security-constraint>

Since the information provided shows that both URLs are responding with a 302 redirect to the HTTPS connector with the same hostname as provided, I'd say that his server.xml configuration is working correctly.
Obviously, there is something in both webapps that is forcing the redirect.
Might I suggest the OP take a look at the web.xml file for the A host to see if he can see that it is indeed requesting the redirect?  (hint: <security-constraint> section.)

To repeat: The name of your virtual host (or one of its aliases) must
match the host header.

You should be using
<Host name="isiee.grasmueck.de" ...>
and
<Host name="srv.grasmueck.de" ...>

No.  The name of your virtual host (or one of its aliases) must match the host header. If they don't match the default host will be used.

Given that you've already told us one of the real host names, you might as well show us the real configuration and the real request if you need help spotting the configuration error.
