What you are suggesting is essentially a hand-made captive portal. I
would be grateful for your mod_rewrite rules, but this will be a last
resort. AFAIK there are implementations of a captive portal in
M0n0wall and pfSense. I've also seen howtos like https://www.unixmen.com/freebsd-10-1-x64-wifi-captive-portal/

But if I can, I'd try a pure WiFi solution first, of course if it
exists.
