[erlang-questions] Nitrogen on several ports

Hi Jesse,

Thank you! That sounds like just what I need. I didn't realise wf:socket() 
would tell me the socket type--very useful!

I am actually using Apache as a reverse proxy to forward port 80 to 8000 
already... my problem is I want to access the *same page* (i.e. same .erl 
file) through http and https, and see different options in each case. I 
suppose I could make two different pages, but that would be more complex and 
less maintainable however I did it (code duplication or a more complex 
module structure). I'm not sure nginx would really solve that problem for

Hi John,

You can get the socket from Nitrogen and from the socket determine its type:

In code that could be something like

is_ssl() ->
   Socket = wf:socket(),
   is_tuple(Socket) andalso element(1,Socket)=:=sslsocket.

Though I personally prefer to throw nginx in front of Nitrogen deal
with that kind of routing (URL-based, anyway).
