Specifying Date-Modified header for .h files in flash memory.

[CelliesProjects]

Is it possible to set a 304 handler on .h files the same way as files served from SPIFFS or FFat?

I now use a construct something like:

...
  server.on( "/", HTTP_GET, [] ( AsyncWebServerRequest * request ) {
    if ( htmlUnmodified( request, date ) ) return request->send(304);
    AsyncWebServerResponse *response = request->beginResponse_P( 200, HEADER_HTML, index_htm, index_htm_len );
    response->addHeader( HEADER_LASTMODIFIED, date );
    request->send( response );
  });
...
static inline __attribute__((always_inline)) bool htmlUnmodified( const AsyncWebServerRequest * request, const char * date ) {
  return request->hasHeader( HEADER_MODIFIED_SINCE ) && request->header( HEADER_MODIFIED_SINCE ).equals( date );
}

This takes about 300ms..
Can this be done better?

esp32? WiFi.setSleep(false)?

Indeed esp32.
WiFi.setsleep()?

[me-no-dev]

yup. be default the wifi sleeps between beacons, that means that you send a packet, but the esp will not get it till the next beacon comes. That slows things down :) set the sleep to false and see if it improves

Well thanks!
11ms.
That closes this issue real good!
