Network Device Monitoring Accessing URL

[mako]

dear community,

is there a possibility to do the following?

i have a device that sends traffic to a custom side in the www

http://www.site.com/auth?id=12345

Is there a possibility to install a module whats checking over that?
short. i have a ring device and this is only calling direct fw.ring.com but i want do local action.

that means i want track if any package will send to fw.ring.com that i can then internal from psense call a url like http://192.168.0.100/homeautomation/?ringTraffic=1

that i can then log them or do any events.

is that possible to track realtime traffice with filters?

thank you so much

@mako
pfSense (Firewall won't do it)
But maybe a Proxy like squid would - (I think squid is installable on pfSense)
