HTTPI, Protocol or small webserver?

[#1]

What is this line in the router used for,
9 HTTPI            tcp                      8080                      enabled
Is it for external web access to the router, ie a small web server,  or is it allowing the HTTPI Protocol to work returning on port 8080.
Or neither ?
Regards
Gary

I believe it's something to do with "web Browsing Interception".
If you disable the above in the GUI then the HTTPI service becomes disabled.

Strange, i have web Browsing Interception disabled, i just checked to make sure.
Very odd.

Using firmware version 8.C.M.0
With web Browsing Interception disabled.

What the hell is goin' on...

Ok so i've restarted my Router earlier today and i do recall turning off that web interception, but it's been up for 44 days and this would be the first time i've restarted it.
I just tried to enable the service from the cli and it appears still disabled after saving etc, so i guess it makes sense that the Router will only make changes after a warm reset etc.
So back to the point in hand, HTTPI=Web Browsing Interception.
