我正在尝试使用创建一个简单的Web应用程序服务器QtWebApp，但是Chrome，Firefox和Chrome浏览器总是两次请求该页面

HttpListener: Listening on port 8084
HttpConnectionHandler (0x642770): constructed
HttpConnectionHandler (0x6436e0): constructed
HttpConnectionHandler (0x642770): thread started
HttpConnectionHandler (0x642770): handle new connection
HttpConnectionHandler (0x642770): received request
request start --> with chrome/firefox/chromium
HttpConnectionHandler (0x6436e0): thread started
HttpConnectionHandler (0x6436e0): handle new connection
request end
HttpConnectionHandler (0x642770): received request
request start --> i'm not refreshing the page but this appear
HttpConnectionHandler (0x6436e0): read timeout occured
HttpConnectionHandler (0x6436e0): disconnected
request end
HttpConnectionHandler (0x642770): read timeout occured
HttpConnectionHandler (0x642770): disconnected
HttpConnectionHandler (0x6436e0): thread stopped
HttpConnectionHandler (0x6436e0): destroyed
HttpConnectionHandlerPool: Removed connection handler (0x6436e0), pool size is now 1
HttpConnectionHandler (0x642770): handle new connection
HttpConnectionHandler (0x642770): received request
request start --> when using curl
request end
HttpConnectionHandler (0x642770): disconnected
HttpConnectionHandler (0x6436e0): disconnected
HttpConnectionHandler (0x642770): read timeout occured
HttpConnectionHandler (0x642770): disconnected
HttpConnectionHandler (0x6436e0): thread stopped
HttpConnectionHandler (0x6436e0): destroyed

我对curl的回答只是：

> GET / HTTP/1.1
> User-Agent: curl/7.35.0
> Host: localhost:8084
> Accept: */*
> 
< HTTP/1.1 200 OK
< Content-Type: text/html; charset=ISO-8859-1
< Transfer-Encoding: chunked
< 
* Connection #0 to host localhost left intact
<html><body>-4417809641995</body></html>

在“ Chrome开发者工具”>“网络”标签上，仅显示了一次请求。

这是浏览器的问题还是控制器的类？

如Florian Sowade评论所述，第二个请求是/favicon.ico
