lws_callback_http_dummy doesn't reply 404 for non-existent mount files #3255

Closed stevensonkd closed 3 weeks ago

stevensonkd commented 3 weeks ago

My application is similar to the minimal-ws-server example. I want to serve static files, so protocols[0] uses lws_callback_http_dummy to handle a mount, and protocols[1] is my WebSocket protocol.

I want my WebSocket clients to be able to negotiate without a protocol name, so per the "Working without a protocol name" section in README.coding.md, I add the per-vhost option "default".

However, if I add this per-vhost option, my application no longer replies with 404 to requests for files that don't exist under the mount. It works as expected for files that exist. But for non-existent files, it doesn't return any data to the client; it just sits there, keeping the connection open (until the 10s timeout elapses).

I can reproduce this with the minimal-ws-server example, just by adding that per-vhost option:

I've tested with Ubuntu 20.04 (lws 3.2.1) and Alpine 3.20 (lws 4.3.3). Same result.

Is this a bug? Or am I doing something wrong here?

What do the detailed logs say?
