running jenkins behind apache2 on subdomain and different port - apache

Question

I am attempting to get a jenkins instance (running on http://localhost:8080/) to be visible at http://ci.domain.com:80/.
Current status:
* Browsing to ci.domain.com gives me the content of domain.com
* Browsing to ci.domain.com:8080 shows jenkins
* Browsing to domain.com:8080 shows jenkins
Ideal status:
* Browsing to ci.domain.com shows jenkins
* Browsing to ci.domain.com:8080 redirects to ci.domain.com
* Browsing to domain.com:8080 does whatever the server would do if there were nothing running on port 8080
My current apache site config (working as expected for shifting traffic to HTTPS) is as follows:
<VirtualHost *:8080>
ServerName ci.domain.com
ServerAlias ci
Redirect temp / http://ci.domain.com/
</VirtualHost>
<VirtualHost *:80>
ServerName ci.domain.com
ServerAlias ci
ProxyRequests Off
ProxyPreserveHost On
AllowEncodedSlashes NoDecode
<Proxy http://localhost:8080/*>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://localhost:8080/ nocanon
ProxyPassReverse / http://localhost:8080/
</VirtualHost>
<VirtualHost *:80>
ServerName domain.com
ServerAlias www.domain.com
DocumentRoot /var/www/domain.com
Redirect permanent / https://domain.com/
</VirtualHost>
<VirtualHost *:443>

<FilesMatch "\.(cgi|shtml|phtml_php)$">

Any help is appreciated.
