The module implements resin's hmux protocol in nginx

nginx-hmux-module's Issues

nginx-hmux-module动态加载

斌哥，nginx-hmux-module啥时候能支持Nginx的--add-dynamic-module功能，使nginx-hmux-module能动态加载

针对新版本nginx，增强hmux模块功能

用户反映：
hmux_next_upstream对non_idempotent的请求处理，以及类似proxy_next_upstream_timeout 和proxy_next_upstream_tries 指令的支持

利用tcpcopy(离线加速功能)压力测试，发现bug一处

需要给ngx_cache_purge打补丁，以支持hmux协议

等需求多的时候，就实现

Cannot get it work with Nginx 1.1.14 and Resin 3.1.12

OS: Debian 6 x64
Nginx: 1.1.14
Resin: 3.1.12

Added to nginx.conf configuration similar to the one you proposed in readme file
Resin works fine and hmux listen on 6800 but Nginx reports connection timeout to upstream when i use hmux_pass

Could you please check the module with the latest Nginx/Resin?

I can provide resin.conf and nginx.conf but actually they are typical, nothing special

ngx_hmux_input_filter

有几个问题想请教一下
1.ngx_hmux_input_filter
数据处理完以后，以什么方式传递给下游
2. keepalive的维持
3.ngx_hmux_process_header 内部具体含义

If you want to pass additional headers to the resin, please use HttpHeadersMoreModule module

Visit http://wiki.nginx.org/HttpHeadersMoreModule for more details
