This is an implementation of a key value store with an HTTP interface. There's also a "forwarding" implementation that proxies requests to an upstream server implementing the same interface.
To build with stack do stack build.
To run with stack do stack exec kv-server.
Set the port with environment variables.
Provide the address of an upstream server to start a forwarder.
USAGE:
env PORT=<PORT> kv-server # start a receiver
env PORT=<PORT> kv-server <RECEIVER-ADDR> # start a forwarder./example.sh demonstrates starting up a chain of three servers (one receiver
and two forwarders). It then demonstrates making several calls to the servers
to show that they work. Finally, it waits for the user to press enter or
ctl+c before shutting down those servers.
