1 Server-proxy data exchange protocol

Overview

Server - proxy data exchange is based on JSON format.

Request and response messages must begin with header and data length.

Passive proxy

Proxy config request

The proxy config request is sent by server to provide proxy configuration data. This request is sent every ProxyConfigFrequency (server configuration parameter) seconds.

name				value type	description
server→proxy:
request				string	'proxy config'
<table>				object	one or more objects with <table> data
	fields			array	array of field names
		-		string	field name
	data			array	array of rows
		-		array	array of columns
			-	string,number	column value with type depending on column type in database schema
proxy→server:
response				string	the request success information ('success' or 'failed')
version				string	the proxy version (<major>.<minor>.<build>)
