WS: Outbound frame fragmentation may result in unexpected continuation frame
If outbound WS data exceeds httpd_websocket_max_frame_size (256 bytes) the data will be sent as chunks using OP_CONTINUATION which can result in the browser closing the WS with exception related to unexpected continuation.
HttpRequest::param(string, int) crashes if param value is not numeric

WebSockets do not work consistently - return key errors due to data corruption
After trying all 3 above mentioned browsers via WebUI, I cannot get my loco to move at all. DCC commands are not being communicated from the UI due to some error/timeout with WebSockets.
If I try to do this from Chromium on my desktop computer, I can control the locomotive no problem.
Add User-Agent and Expect header parsing
Uploading firmware via curl will fail unless you specify it as:
curl --form firmware=@build/firmware.bin -H 'Expect:' -H 'User-Agent:'
Websocket: handler is invoked for disconnect prior to connect
If the handshake process fails the websocket handler is being invoked during disconnect even though it has not been invoked for the connect event:
[WebSocket fd:52] read-error (22: Invalid argument), disconnecting (handshake)

Add support for ETag header

Out-of-memory issue when allocating a http request header buffer
Trying to setup a 512 byte buffer for reading the http request headers and failing to allocate it.
There could be an IDF setting that can be used to suppress the abort() call and instead just return nullptr.

WS: Rework to queue frames rather than use a string buffer for text messages
The current approach can lead to out-of-sequence deliveries leading to the following error being shown in the browser when multiple text based messages are being sent in excess of the maximum frame size:
index.html:336 WebSocket connection to 'ws://10.0.0.189/ws' failed: Received start of new message but previous message is unfinished.
connectWebSocket @ index.html:336
