I really find this rather surprising. Ocaml has a very decent wrapper
around Openssl that works rather well so it can't be that hard.

But why shouldn't it should go into Network.HTTP? All I want to do
is a HTTP POST of text/xml data to a HTTPS server and retrieve the
text/xml data response and the HTTP response code. Whether that 
URL is HTTP vs HTTPS shouldn't matter.

With a sane API I should just be able to change from a HTTP url to 
a HTTPS url and have it JustWork (tm). To have to use a different
library depending on whether I'm doing http vs https is just

Sorry, thats way too cludgy for my application.

I've used openssl directly from C and C++ so  I know its doable, but
I consider openssl a real blemish on the FOSS world.

There is however this:
