ssl setup problem (contd.)

[Chandrashekhar Mullaparthi]

Hi,

I don't have a solution for your problem but I can suggest an 
alternative.

Unless you can really think of a reason to have SSL handling within the 
erlang node (like getting access to client certificates), consider 
using stunnel which is available from http://stunnel.org

You get several advantages doing it this way.

- SSL handling is done in separate UNIX process so you can take 
advantage of a multi-CPU machine if you have one.
- stunnel is quite mature and works pretty well. I haven't used it 
under a heavy load but there are other systems in our network which use 
this for pretty heavy duty stuff.

One down side is that you then can't fit it into the OTP release 
framework. A way around it is to write a wrapper application which 
launches stunnel and monitors it.

cheers
Chandru
