You can improve your .html scripts if you use "relative" paths instead of hardcoded ones. Eg. instead of "http://192.168.0.2/proc/empeg_notify?button=20df07.S just use "/proc/empeg_notify?button=20df07.S".

Note that the ".S" is totally ignored, so it should get removed.

And with v128 hijack, this all becomes: "/?button=20df07"

Cheers
