我使用SPDY模块从源代码编译了Nginx 1.4.3.

但是当启用SPDY时,它似乎打破了我的’Vary：Accept-Encoding’标题.

我的Nginx配置：

./configure
--conf-path=/etc/Nginx/Nginx.conf
--pid-path=/var/run/Nginx.pid
--error-log-path=/var/log/Nginx/error.log
--http-proxy-temp-path=/var/cache/Nginx/proxy_temp
--http-fastcgi-temp-path=/var/cache/Nginx/fastcgi_temp
--http-uwsgi-temp-path=/var/cache/Nginx/uwsgi_temp
--http-scgi-temp-path=/var/cache/Nginx/scgi_temp
--http-log-path=/var/log/Nginx/access.log
--with-http_ssl_module --prefix=/usr
--add-module=./Nginx-sticky-module-1.1
--add-module=./headers-more-Nginx-module-0.23
--with-http_spdy_module

我的`Nginx.conf’文件：

启用/禁用SPDY时的标头结果：

如您所见,当启用SPDY时,Vary：Accept-Encoding标头会消失.

这是我的Nginx.conf配置方式的问题吗？
