In my pfsense box, I'm using Captive Portal (connected to RADIUS MS AD) and Squid setup as Transparent Proxy.
I would like to know if it is possible for me to maybe "inject" a small HTML DIV on the top portion of the browser where it displays Captive Portal information (like login name, session time, company logo and most importantly a logout button)?
pfSense Captive Portal CANNOT do this, I believe. Can Squid do it? Or perhaps some other way?
