Subject: ref: Move net/http

I was young and naive, fasthttp does not fit my needs and make
development slower. I'll move to net/http since it has a wider support
and will spare some time on implementation detail things (like CSRF). It
will allow me to reduce a bit of the code since there may be lib for
handling cookie encryption and auth in general.
