For the moment only for the client side. BUT once we test this enough and have the confidence that it works without side effects we can integrate it into the server and have the best http server in the ESP8266 land :)
@slaff BTW, at the VERY ancient times, ZX81 (Z-80 based) I have seen a FORTH interpreter, it was ~1kB code size. Maybe it is worth to write something like that for ESP? (as of my experience LUA interpreter was not stable).
