upstream: grant recovery time to backend server

i have a load balancing setup running with nginx in front and 2 tomcats as

upstream backend  {

Runs fine so far, but from time to time one of the tomcats crashes and needs
to be restarted. As soon as nginx notices that the tomcat is coming up,
nginx starts to forward requests to the starting-up tomcat. But it would be
better that the tomcat starts up completly before nginx starts sending
requests to it.

Is there any possibility to grant a recovery time to a backend server before
the backend receives requests? I.e. something like "nginx: hey, i noticed
that the formerly crashed backend server is coming up, but i'll wait 300s
before sending requests to it"?

thx in advance
