Apache Tomcat将使用非阻塞HTTP协议关闭文件下载的连接
[英]Apache Tomcat will close connection on file download with non blocking http protocol
问题描述
Per default the protocol in server.xml is configured as protocol="HTTP/1.1" . 
默认情况下，server.xml中的协议配置为protocol =“ HTTP / 1.1” 。 with newer tomcat versions this will use a non blocking protocol if possible. 对于较新的tomcat版本，如果可能，它将使用非阻塞协议。
Problem: Setup Tomcat (8.0.28) with default settings. 问题：使用默认设置安装Tomcat（8.0.28）。 Copy a file in a webapp eg webapps/root and download the file with limited speed to simulate a slow modem download. 在webapp（例如webapps / root）中复制文件，并以有限的速度下载文件，以模拟缓慢的调制解调器下载。
wget http://xxx.xxx.xxx.xxx:8080/xxxxxxx/7.zip --limit-rate=1k
Connection will be closed always after 6minutes and 24seconds 连接将始终在6分钟和24秒后关闭
Saving to: ‘7.zip’
7.zip 0%[ ] 767.99K 1.00KB/s in 6m 24s
2015-10-28 17:27:39 (1024 B/s) - Connection closed at byte 786426. Retrying.
if i change the protocol to (blocking): 如果我将协议更改为（阻止）：
protocol="org.apache.coyote.http11.Http11Protocol"
everything is fine and the download will complete with slow speed. 一切都很好，下载将以缓慢的速度完成。
What could be the issue? 可能是什么问题？

It is a known limitiation with the new apache protocols. 这是新apache协议的已知局限性。
The only solution to have a stable connection below 64kb/sec is to change the settings: socket.txBufSize (smaller) and connection timeout (higher). 低于64kb / sec的稳定连接的唯一解决方案是更改设置：socket.txBufSize（较小）和连接超时（较高）。 for more details check: https://bz.apache.org/bugzilla/show_bug.cgi?id=58565 有关更多详细信息，请检查： https : //bz.apache.org/bugzilla/show_bug.cgi?id=58565
