In testing the CHUNKED html send implementation in the current GitHub version I have found that it is not complete because it does not send a 0bytes body content message to the client to tell the browser to TERMINATE the chunked transfer session. This causes the browser connection to remain active for an extra 2 seconds or so even though the entire HTML chunked transfer is complete This slows down the browser! In looking at FireFox dev tools a chunked transfer of 5*3000byte HTML pieces is taking over 2300ms to complete with the later 2 seconds the browser is just sitting there waiting for its own transfer time out to kicks in. After modifying the Webserver library I can have the transfer/transaction complete in just 150ms. ADD to ESP8266WebSwerver.cpp ``` void ESP8266WebServer::endChunkedContent() { const char * end = "0\r\n\r\n"; _currentClient.write(end, 5); } ``` ADD to ESP8266WebServer.h `void endChunkedContent(); //Call this last when doing multiple server.sends (in CHUNKED trasnfers)` Then to do proper CHUNKED html transfers using the following method ``` server.setContentLength(CONTENT_LENGTH_UNKNOWN); //Enable Chunked Transfer server.send(200, "text/plain", webPagePart1()); //Send first part WITH header server.sendContent(webPagePart2()); //Send next chunk of html server.sendContent(webPagePart3()); //Send next chunk of html server.endChunkedContent(); //Tell browser no more content is coming ```
