Example 1 with HostnameResolutionException

use of com.nike.riposte.server.error.exception.HostnameResolutionException in project riposte by Nike-Inc.

the class StreamingAsyncHttpClient method resolveHostnameToInetSocketAddressWithMultiIpSupport.

/**
 * Returns an {@link InetSocketAddress} for the given hostname and port - if the DNS for the hostname has multiple
 * IP addresses associated with it then the returned IP address will be randomly chosen from the available IPs.
 * <p/>
 * This is necessary to properly distribute traffic among all the IPs rather than firehosing a single one. For
 * example, Amazon ELBs function by associating multiple IPs with the ELB's DNS. Without this method all traffic
 * would pipe to only one of an ELB's IPs, and since ELBs scale up based on aggregate traffic over all IPs,
 * firehosing one IP means the ELB would never scale up even though it's being overloaded.
