Subject http request (no only session) replication in cluster
Date Tue, 11 Jun 2013 13:54:05 GMT
What can be done to guarantee failover in below scenario:

2 tomcats behind cisco loadbalancer
1 http request can last very long about 50 seconds - response from
webservice can take so long
load is 200 requests per second
I must response in max 4 seconds more than backing webservice

is there something like http request replication ?

50 s * 200 req/s = 10.000 pending requests

if one tomcat is eg killed, can in any way other tomcat serve his requests ?

is there any out of the box solution, eg similar to session replication ?


is it possible to save socket to database, or send it via network?
