Hello, I am using haproxy-1.6 with Lua. I have a use-case where I want to set the destination (backend server) very dynamically, based on certain layer 7 information (I am trying to avoid updating haproxy configuration and make it complicated with a ~100 domain names and their corresponding backend server name and do a map lookup, I want lua to do it ) eg: from lua, based on certain layer 7 information I want to change the backend server (set destination) it should connect to.. if Host is ‘example.test.com’; then backend is test1.server.com elsif Host is ‘example2.test.com; then backend is test2.server.com I want to keep the haproxy config simple and have only the Listen directive listed and take more control of the request flow from the LUA code. The ATS traffic server does provide such functionality through the LUA API hook to override backend server dynamically from Lua end if ts.client_request.header[Host] == 'example.test.com' then ts.client_request.set_url_host( test1.server.comts.client_request.set_url_port(80)elsif ts.client_request.header[Host] == 'example2.test.com' then ts.client_request.set_url_host( test2.server.com ) ts.client_request.set_url_port(80)end Is it possible to do the same using Haproxy and Lua?
Thank you, Mrunmayi
