Coin connection timeout

The route which goes from http://coin/coin/ or http://coin.intra.qt.io/coin/  to http://10.212.3.36:8080/coin/ (dns or proxy?) Causes timeouts as some coin requests take occasionally long time. Straight connection to ip address does not cause timeouts. Default timeout seems to be 60 seconds and requests might take up to 15 minutes while coin is at high load. It is cumbersome for user to keep sending the requests while one would be enough and also piling unnecessarily at Coins end. Could this be adjusted to fit what Coin currently needs.
