From 9e61e60b0c404c2d12a6a582f24dce5dc6e97dab Mon Sep 17 00:00:00 2001 From: Assaf Inbal Date: Sun, 3 Jan 2016 21:06:21 +0200 Subject: [PATCH] A content length of zero should also be sent This is needed since when the content-length header is not sent the clients will wait for data anyways. Sending a content length of zero will tell the client not to expect any content and it will close the connection immediately. --- libraries/ESP8266WebServer/src/ESP8266WebServer.cpp | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) diff --git a/libraries/ESP8266WebServer/src/ESP8266WebServer.cpp b/libraries/ESP8266WebServer/src/ESP8266WebServer.cpp index 77e59af6a..0465db4c5 100644 --- a/libraries/ESP8266WebServer/src/ESP8266WebServer.cpp +++ b/libraries/ESP8266WebServer/src/ESP8266WebServer.cpp @@ -213,11 +213,10 @@ void ESP8266WebServer::_prepareHeader(String& response, int code, const char* co content_type = "text/html"; sendHeader("Content-Type", content_type, true); - if (_contentLength != CONTENT_LENGTH_UNKNOWN && _contentLength != CONTENT_LENGTH_NOT_SET) { - sendHeader("Content-Length", String(_contentLength)); - } - else if (contentLength > 0){ + if (_contentLength == CONTENT_LENGTH_NOT_SET) { sendHeader("Content-Length", String(contentLength)); + } else if (_contentLength != CONTENT_LENGTH_UNKNOWN) { + sendHeader("Content-Length", String(_contentLength)); } sendHeader("Connection", "close"); sendHeader("Access-Control-Allow-Origin", "*");
