I have following configuration,

global  
log 127.9.9.1 local0 #debug  
log /dev/log local0  
log /dev/log local1 notice  
chroot /var/lib/haproxy  
stats socket /run/adminha.sock mode 600 level admin  
stats timeout 30s  
user haproxy  
group haproxy  
daemon

defaults  
log global  
mode http  
option httplog  
timeout connect 5000  
timeout client 2m  
timeout server 2m

frontend outwards-haproxy  
bind \*:80  
bind \*:443 ssl crt /pathgiven no-sslv3  
redirect scheme https code 301 if !{ ssl\_fc }  
stats enable  
stats uri /stats   
stats enable  
stats uri /stats  
stats hide-version  
stats auth admin:1234

```
acl is_off url_beg /smoke1/
use_backend offapp if is_off

```

backend offapp  
balance roundrobin  
option redispatch 1  
retries 2  
cookie platform\_extension\_sessionid prefix nocache  
server off1 host1:8443 check ssl verify none cookie s1  
server off2 host2:8443 check ssl verify none cookie s2

I m getting 503 if one of backend server is stopped. Why it is not seamlessly transferring connection ?? even if i have 2 nodes
