Login data lost when using Apache's mod_proxy

Issue

• Given a current setup of:

Client browser -> Apache --> mod_proxy -> App. servers

• Inside the relevant VirtualHost section, the following Location section works:

  <Location /app>
          ProxyPass http://w.x.y.z/app
          ProxyPassReverse http://w.x.y.z/app
  </Location>

• But when changing said section to the following, the web application continuously asks for login information:

  <Location /intra/app>
          ProxyPass http://w.x.y.z/app
          ProxyPassReverse http://w.x.y.z/app
  </Location>
