RE: mod_jk or mod_proxy_ajp - encryption benefits ?‏

[James Ellis]

I have done some goog'ling on IPSec and VPN and I have found three 
possibilities:
 
1) OpenSSH and Port Forwarding
 
2) OpenVPN
 
3) Stunnel (thanks little voice)
 
What concerns me about all three options is error handling.  If my OpenSSH or 
OpenVPN or Stunnel connection failed/timed out, the whole site would go down.  
There would have to be a VERY good and almost instant reconnection taking place.
 
I am also concerned about performance.
 
Any comments?
