Essentially I am having httpd reroute http requests to a certain location to Tomcat (http://localhost:8080/app/). This works fine using the ProxyPass and ProxyPassReverse functionality. When doing this with https however, my Tomcat instance is complaining that it does not know how to deal with the secure connection. Basically I am trying to have requests that come in on to be decrypted by apache and then sent over to http://localhost:8080/app/ . The relevant virtual host I have set up is this:

I hope that is clear. If you need more clarification, I can provide it.

<VirtualHost *:443>

        #  General setup for the virtual host

        ErrorLog /var/log/apache2/mydomain-ssl-error_log
        TransferLog /var/log/apache2/mydomain-ssl-access_log

        #   SSL Engine Switch:                                                                                                                                                                 
        #   Enable/Disable SSL for this virtual host.

        SSLProxyEngine on

    #   URLs to forward                                                                                                                                                                    
        <Location /folder>
          ProxyPass http://localhost:8080/app/

You don't provide the error message or a description of the Connection setup on the Tomcat side, so I'm guessing here:

Personally, I use AJP with Tomcat because it works better for my brain, or maybe I just have trouble with Java setups.

Sorry if it was not clear. I do not want Tomcat to deal with any encryption. I want apache to send the unencrypted message to Tomcat and then encrypt it on the way back to the client. Is this not possible with mod_proxy? – thatidiotguy Jul 23 '12 at 20:07
Not wanting Tomcat doing SSL is clear. The specific error message, and your Tomcat config, are not specified. – khoxsey Jul 23 '12 at 20:11
Is that enough? Or do you need engine or another directive? – thatidiotguy Jul 23 '12 at 20:35
That is enough information to show that you are configured with secure="true", so Tomcat thinks it is handling SSL. Try reconfiguring Tomcat's server.xml as described in the first link I provided. – khoxsey Jul 23 '12 at 20:39

Get rid of the 2nd Tomcat connector on port 8443 altogether. Change the redirectPort in the other one to 443. Get rid of the SSLProxyEngine directive, or turn it off. At present you are (a) able to receive HTTPS in Tomcat, which you don't want, and (b) sending HTTPS from Apache, because of the SSLProxyEngine, which you also don't want.

You will have great trouble redirecting /folder to /app, because the Tomcat web apps will generate internal self-referencing URLs starting with /app. There are various solutions such as ProxyPassReverse and mod_proxy_http, but in my opinion the cure is worse than the disease. Make them the same, e.g. /app /app, then you can get rid of ProxyPassReverse as well. Try to make your Apache completely transparent in terms of URLs, which may mean adjusting the names of the Tomcat web apps.
