Hi all,

In a release deployment I would like to buffer client requests that come  
to  
nginx(in reverse proxy) mode to be buffered for possibily 2-6 seconds  
while  
a pdsh request is sent to switch symlinks on the back end server to  
/var/www/html/current .

After the switch is complete, I would want to release the buffering  
while  
avoiding a herd clash.

Is this possible in nginx? Can someone help?
