3scale

I need a API gateway for my websocket application. Analyse and identify unusual requests from certain IP Quotas and Rate Limiting Statistics Free or commercial Solid performance The sub-protocol of my WebSocket is WAMP, so I am afraid there is no existing product to do the job. I intend to develop one and suppose it will work in this way: There is a proxy (NGINX or HAProxy) installed between my client application and my websocket server The proxy duplicates the request/response to another app, which I call monitor The monitor app analyses the flow and control the proxy to limit/block certain

I am doing a proof of concept to demonstrate how we might implement 3scale in our stack. In one example I want to do some POST request body manipulation to create an API façade that maps what might be a legacy API format to a new internal one. Eg. change something like { "foo" : "bar" , "deprecated" : true } into { "FOO" : "bar" } The Lua module docs for content_by_lua , which seems like the appropriate method say Do not use this directive and other content handler directives in the same location. For example, this directive and the proxy_pass directive should not be used in the same location.
