HEADERS Content-Security-Policy on APACHE HTTPD with Proxypass and Proxypassreverse

Question

I need to include headers from CSP within Apache HTTPD.

Configuration I currently have:

servor_backend

    IP: 10.10.10.11
    WebServer: Apache Tomcat 6
    Port: 8080 (http), 8009 (ajp)

servor_frontend

    IP: 10.10.10.12
    WebServer: Apache HTTPD
    Port: 82 (http), 8443 (https)

My configuration file in /etc/httpd/conf.d/www.exemplo.com.br.conf :

<VirtualHost *:82>
  ServerName www.exemplo.com.br
  Redirect permanent / https://www.exemplo.com.br:8443/
</VirtualHost>

<VirtualHost _default_:8443>

  ServerName www.exemplo.com.br
  SSLEngine on

  SSLCertificateFile /etc/ssl/certs/exemplo.com.br.crt
  SSLCertificateChainFile /etc/ssl/certs/exemplo.com.br-ca.crt
  SSLCertificateKeyFile /etc/pki/tls/private/exemplo.com.br.key

  TimeOut 1800
  ProxyTimeOut 1800

  ProxyPass / http://10.10.10.12:8080/
  ProxyPassReverse / http://10.10.10.12:8080/
</VirtualHost>

I tried to use the documentation Apache HTTP to include headers, but did not take effect.

Configuration I used:

 LoadModule        headers_module          modules/mod_headers.so

<VirtualHost *:82>
  ServerName www.exemplo.com.br
  Header set Content-Security-Policy "upgrade-insecure-requests;"
  RequestHeader set Content-Security-Policy "upgrade-insecure-requests;"
  Redirect permanent / https://www.exemplo.com.br:8443/
</VirtualHost>

...

Since I use a Proxypassreverson, I cannot make use of the .htaccess.

I need a path indication, or guidance on how to proceed. Any comments are welcome.
