This simple proxy allows one to simulate different delays between different network nodes. Basic useful feature list:
- Intuitive YAML based configuration.
- Supports HTTP, HTTPS, and SQL Proxying.
- Allows delaying (simulating) slow SQL servers.
- Supports any TCP based Database interfaces e.g.MySQL, Oracle(tm) .
- Dynamic changes in delay parameters via REST API.
- Uses Netty for IO handling.
- Uses WSO2 MSF4J for REST API publishing.
- High performance, Low memory footprint, low CPU and resource usage.
- Can run headless.

proxies:
proxiesConfig:
name: "My Sample Proxy"
restApi:
listenPort: 8090 # Port which REST API (MSF4J) listens(optional, default 8080)
listenAddresses: "0.0.0.0" # machine IP Addresses or Host names to listen (not supported)
proxies:
- name: "To WSO2 IS" # Unique human readable name
enable: true # enable or disable this proxy
type: TCP # Proxy type, TCP or SQL
in: # Inbound configuration
port: 10080 # Inbound listening port
host: localhost # Inbound listening IP (currently all IPs)
out: # Outbound configuration
port: 80 # Remote port to be proxied
host: www.google.lk # Remote host to be proxied
delay: # Delay configurations (only one delay set can be configured currently)
match: all # - Unused
min: 10 # Minimum Delay in milliseconds
avg: 30 # Average delay in milliseconds
max: 130 # Maximum delay in millisecondsThe delay is randomized on average delay. However it will be in between min and max value.
Set min, max or average delay
http://<host>:<port>/configure/proxy/{index}/delay/{match}/<min|max|average>/{value}
e.g.
http://<host>:<port>/configure/proxy/0/delay/match/min/3
Sets the minimum delay 3 milliseconds for the proxy at index 0. ("match" term currently unused and can put any string.)
