The proxy will rely on distinction between GET and POST to know whether to cache. More importantly, your enterprise Load Balancer with timeout and failover configured will feel free to repeat a GET request internally to a different server when the first server takes too long to respond. For a POST, it will instead throw an error to a user and perhaps trigger internal alert. And if you think that's not a big deal, wait until your bank does a double international money transfer because their trigger call was implemented accidentally as a GET request and the network latency was bad. And hope, just hope, that they are not running 10 different servers behind the firewall and therefore falling over 10-1 times.... (true horror story from my tech support days).
