You can serve parts of your filesystem at part of\n+the URL space using mounts, the dummy http callback will do the right thing.\n \n It's much preferred to use the \u0022automated\u0022 v2.0 type scheme, because it's less\n code and it's easier to support.\n \n You can see an example of the new way in test-server-v2.0.c.\n \n-If you just need generic serving capability, consider not writing any server code\n-and instead use lwsws and writing your user code in a standalone plugin. The\n-server is configured for mounts etc using JSON, see README.lwsws.md.\n+If you just need generic serving capability, without the need to integrate lws\n+to some other app, consider not writing any server code at all, and instead use\n+the generic server `lwsws`, and writing your special user code in a standalone\n+\u0022plugin\u0022. The server is configured for mounts etc using JSON, see\n+./READMEs/README.lwsws.md.\n+\n+Although the \u0022plugins\u0022 are dynamically loaded if you use lwsws or lws built\n+with libuv, actually they may perfectly well be statically included if that\n+suits your situation better, eg, ESP32 test server, where the platform does\n+not support processes or dynamic loading, just #includes the plugins\n+one after the other and gets the same benefit from the same code.\n+\n+Isolating and collating the protocol code in one place also makes it very easy\n+to maintain and understand.\n+\n+So it if highly recommended you put your protocol-specific code into the\n+form of a \u0022plugin\u0022 at the source level, even if you have no immediate plan to\n+use it dynamically-loaded.\n+\n+@section writeable Only send data when socket writeable\n+\n+You should only send data on a websocket connection from the user callback\n+`LWS_CALLBACK_SERVER_WRITEABLE` (or `LWS_CALLBACK_CLIENT_WRITEABLE` for\n+clients).\n+\n+If you want to send something, do NOT just send it but request a callback\n+when the socket is writeable using\n+\n+ - `lws_callback_on_writable(context, wsi)` for a specific `wsi`, or\n+ \n+ - `lws_callback_on_writable_all_protocol(protocol)` for all connections\n+using that protocol to get a callback when next writeable.\n+\n+Usually you will get called back immediately next time around the service\n+loop, but if your peer is slow or temporarily inactive the callback will be\n+delayed accordingly. Generating what to write and sending it should be done\n+in the ...WRITEABLE callback.\n+\n+See the test server code for an example of how to do this.\n+\n+Otherwise evolved libs like libuv get this wrong, they will allow you to \u0022send\u0022\n+anything you want but it only uses up your local memory (and costs you\n+memcpys) until the socket can actually accept it. It is much better to regulate\n+your send action by the downstream peer readiness to take new data in the first\n+place, avoiding all the wasted buffering.\n+\n+Libwebsockets' concept is that the downstream peer is truly the boss, if he,\n+or our connection to him, cannot handle anything new, we should not generate\n+anything new for him.
