 WRP originally started as true http proxy. However this stopped working because the whole internet is now encrypted thanks to [Let's Encrypt](https://en.wikipedia.org/wiki/Let%27s_Encrypt). Legacy browsers do not support modern SSL/TLS certs as well as [HTTP CONNECT](https://en.wikipedia.org/wiki/HTTP_tunnel#HTTP_CONNECT_method) so this mode had to be disabled.
 
-### Will you support http proxy mode in future?

 Some efforts (ssl strip) are under way but it's very [difficult](https://en.wikipedia.org/wiki/HTTP_tunnel#HTTP_CONNECT_method) to do it correctly and the priority is rather low.
