Windows 2003服务器上的Apache版本为2.2.17
以下是它的路由：
user -> AA.com request -> Apache proxy server on AA.com network -> BB.com
直到一周前，这个工作没有问题，没有对Apache配置或其间的任何网络元素进行任何更改。
启用调试，我看到了：

1。）我认为这是关键错误：** [debug] mod_proxy_http.c(1458): [client <<IP-2-of-internal-nw-AA.com>>] proxy: NOT Closing connection to client although reading from backend server BB.com:443 failed.**
BB.com的问题不在于回复数据吗？
这是AA.com上apache配置的一部分： ServerName AA.com ServerAlias AA.com
CacheEnable disk /context

CacheMaxFileSize 10485760
CacheIgnoreHeaders Set-Cookie
SSLProxyEngine On
ProxyPreserveHost On

#########################
ProxyPass /context https://BB.com/context disablereuse=on retry=0
RequestHeader set X-Forwarded-Proto "https"
SetEnv force-proxy-request-1.0 1
SetEnv proxy-nokeepalive 1

任何指针？
1.）ProxyTimeout不正确吗？
2.）这些是建议的解决方案，因此补充说：
SetEnv force-proxy-request-1.0 1
SetEnv proxy-nokeepalive 1
