Webproxy forcing landing page

NethServer Version: 7
Module: webproxy
Hi, Im new here, so might be talking jiberish.
I am using nethserver7 as my organisations gateway, with 2 providers. however my boss wants me to setup a notice board. ie, all clients will get the notice board as soon as they open their web browser, the first time. there by forcing users to read the notices.
So my question, can the webproxy in N7 force a landing page?


As far as I know it’s not implemented in NethServer, but maybe it’s possible to configure a squid’s splash page to achieve what you want.
