Hello Abhinav,

Thanks for the inputs. Could you pl let me know where to get the www-lib
from? Can I simply download it from somewhere?

Thanks once again,
Kaustubh

If you are going to use solaris 2.6, 2.7, 2.8 then you need to install
EGD/PRNGD (Entropy gathering daemon) or install patch from solaris to
support
/dev/random.  Without this you application wont work (also on IBM and HP).
If
you use EGD/PRNGD then you have to add following line in HTSSL_init
 RAND_egd(prngd_socket); (with surrounding ifdef for platform).  You may
also
need to do more work if you plan to user identity with your client code.
For
details on using trusted certs identity, key file. look at openssl examples.
