BBC 中文并不是二级域名的方式，而是直接 http://www.bbc.co.uk/chinese 这种形式，如果配置cow的被墙和直连

一连被墙网站就crash

~/.cow/blocked是否可以支持正则或简单的星号匹配？

当然也包括~/.cow/direct

类似_.google.或.youtube._这种规则实在太有用了

Avoid DNS pollution

Use the method in pydnsproxy.

PAC file not working on iOS

This is weird ...

site_blocked.go 和 site_direct.go 能否独立出来？

site_blocked.go 和 site_direct.go 能否独立出来？
成为site_blocked.json 和 site_direct.json 或.txt文本格式，这样便于编辑和添加网址。

ISP或公司防火墙有时会屏蔽百度网盘、迅雷离线、迅雷看看、淘宝天猫、微博等，这些网址一直处在site_direct.go里。

下载master.zip源码再编译，有诸多不便，如需要安装go语言程序、个人水平、电脑使用环境因素（如有的机器权限不够没法安装程序等）等。

有关 COW 如何检测被墙网站

“
COW 如何检测被墙网站

COW 将以下错误认为是墙在作怪：

服务器连接被重置 (connection reset)
创建连接超时
服务器读操作超时
”

下面这一条归类到创建连接超时或服务器读操作超时当中了吧，
错误 324 (net::ERR_EMPTY_RESPONSE)：服务器已断开连接，且未发送任何数据。
单独作为一条，检测效率是否更高效。

Snova / GSnova 增强的PAC实现SPAC（Special Proxy Auto Config）
http://code.google.com/p/snova/ https://github.com/yinqiwen/gsnova
默认的智能代理127.0.0.1:48100，全局代理127.0.0.1:48102
使用智能代理48100端口翻墙效果很好。好像是使用gfwlist转换成pac，我没看明白。

wallproxy
http://code.google.com/p/wallproxy/
http://code.google.com/p/wwqgtxx-goagent/ 中的 wwqgtxx-wallproxy-Release-noFirefox-1.3.7z 使用的就是wallproxy ，启动后在系统右下角托盘处，单击设置代理打开代理设置对话框。

默认的智能代理127.0.0.1:8086，自动代理pac（自动更新）作用于 IE浏览器代理设置， internet属性 →局域网设置 → 使用自动配置脚本 PAC。

wallproxy智能代理比自动代理pac 要强大，有些被墙的网页，自动代理pac模式下打不开，智能代理可以很顺利打开。使用智能代理8086端口翻墙效果很好。

希望作者观察对比一下，他们的检测机制如何，融合wallproxy 、Snova的优点。

请求增加多个shadowsocks 服务器之间负载均衡的功能

我的cow放在公司内网供集体使用。最近发现连接变的缓慢了，换到另外一台同机房的shadowsocks 服务器就正常。应该是长城会对连接流量进行监控，发现异常就将让客户端和服务器的连接变的困难。希望有负载均衡功能

cow和shadowscocks两个都有一定的概率开机启动时没有最小化

求解决这个问题。

Support multiple user authentication

Hi Yufei,

When I tried to run multiple instances of cow, one for a port, I received the following error.

runtime: panic before malloc heap initialized
fatal error: runtime: cannot allocate heap metadata

By searching Google I found these links.

https://code.google.com/p/go/issues/detail?id=5236
https://codereview.appspot.com/9791044/

These explanations do not make sense to me. I hope you will have a solution:-)

Also is it possible to open multiple ports in one config file so that I only need to run one instance? And with different authentication for each port? A proposed config format would be:

listen = xxx.xxx.xxx.xxx
portUserPasswd = 1080:username1:password1
portUserPasswd = 1081:username2:password2
portUserPasswd = 1083:username3:password3

Thanks!

0.6.3出小错 (HTTP 100 Continue 响应处理不当)

http://www.521000.com/bbs/
这个网站搜索时出错：
[Error] Bad request
WSARecv tcp 127.0.0.1:7777: i/o timeout

给大大一个建议

希望能变成C语言源码，移植性更强
支持透明代理 iptables类的转发支持

规则上能否支持正规表达式？类似于squid
白名单黑名单功能？可以用来过滤广告什么的
最重要的就是移植openwrt系统下

too many open file error from socks server

After using for a while saw this error message. Need to investigate.

cow访问taobao alipay的网站不正常

有一次出现了这个:

[Error] i/o timeout

HTTP Request GET trade.taobao.com:80/trade/itemlist/list_bought_items.htm?spm=a1z09.2.0.21.q73lIs

Direct connection failed, always direct site.

后端代理直接支持 SSL Proxy？

可否增加对 SSL proxy 直接作为 parent proxy？如此可以省掉先用 stunnel 转换：）

Support ssh password

Some SSH server does not support public key authentication.

建议~集成DNS proxy through sock5 server

cow的设计**非常好~~一个软件搞定所有问题~~不过DNS污染和注入还是会影响safari的和其他软件dns解析，作者大大能不能集成上一个dns服务器，如果发现被墙网站的dns请求就通过加密代理找支持tcpdns解析的域名服务器解析，否则就走本地？

can't create shadowsocks connection for xxx : too many open files

can't create shadowsocks connection for: www.facebook.com:443 dial udp 8.8.8.8:53: too many open files
运行了半个月出现了这个问题，然后无法继续代理

support dd-wrt

it's great to install cow on router like dd-wrt

Pipelining may lost request

Need to correctly support request retry.

貌似我这样写的没有生效

没有生效，因为有时候本地开发的站有点慢，然后给识别成需要代理了 =.=

Support proxy authentication

仅对私有 IP 总是直连

COW 0.6.3 rc.txt 配置如下：
listen = 127.0.0.1:7777
alwaysProxy = false
loadBalance = backup
#8087 goagent
#10000 apjp
#7070 ssh
#1080 shadowsocks

httpParent = 127.0.0.1:8087
httpParent = 127.0.0.1:10000
socksParent = 127.0.0.1:7070
socksParent = 127.0.0.1:1080
dialTimeout = 3s
readTimeout = 4s

addrInPAC = 127.0.0.1:7777

虽然 cow 内置了 shadowsocks 支持，为了便于shadowsocks-local.exe进程限速，而不是shadowsocks流量包含在cow.exe进程内，所以另外使用shadowsocks-go开启shadowsocks代理。

“
指定多个二级代理时使用的负载均衡策略，可选策略如下
backup: 默认策略，优先使用第一个指定的二级代理，其他仅作备份使用
hash: 根据请求的 host name，优先使用 hash 到的某一个二级代理
一个二级代理连接失败后会依次尝试其他二级代理
失败的二级代理会以一定的概率再次尝试使用，因此恢复后会重新启用
loadBalance = backup
”

问题：
1

addrInPAC = 127.0.0.1:7777 与 addrInPAC = 127.0.0.1:7777 一样，cow-taskbar窗口显示PAC都照样添加。

2
8087 goagent 不稳定，有时出现403、500错误，但过几分钟后就正常，但是cow几天后都没有尝试使用。
“失败的二级代理会以一定的概率再次尝试使用，因此恢复后会重新启用”
不知道此处的概率计算怎么设置的，只能每行用#屏蔽其他三个代理，cow才使用8087 goagent。
建议在rc.txt中可以设置成cow重新载入或重新启动后，就能从头开始依次尝试使用各个二级代理，包括失败的二级代理。

有时候并不是某个二级代理本身有问题，是我没有启动它或上网所用网络不稳定，cow可能就认为这个二级代理失败不再使用它。

3
httpParent = 127.0.0.1:8087
httpParent = 127.0.0.1:10000
socksParent = 127.0.0.1:7070
socksParent = 127.0.0.1:1080
使用一段时间后，修改为
socksParent = 127.0.0.1:1080
httpParent = 127.0.0.1:8087
httpParent = 127.0.0.1:10000
socksParent = 127.0.0.1:7070
无效。
依然按照先前的顺序加载二级代理，8087、10000、7070二级代理如果没打开，尽管1080 shadowsocks打开了且有效，也排在第一位
但cow此时却跳过第一位的1080 shadowsocks，依次尝试到7070二级代理就宣告失败了。
要说cow对rc.txt有缓存也不对，因为每行用#屏蔽却可以生效。

4
对于直接用ip地址访问的网站一直是Using direct connection. 造成自动翻墙失败。

希望改进cow，感谢作者编写功能强大实用的二级代理调度和直接内置支持shadowsocks登陆的软件！

Support HTTP 1.0

There are still web sites using HTTP 1.0 servers, e.g. www.wpxap.com (reported by Naruil).

可能有内存泄漏？

在1G 内存的linux机器运行，运行前内存有900MB 左右，运行4个小时后程序崩溃，报错：fatal error: runtime: out of memory。
客户端连接大概有20来个

Not correctly handle server using closed connection to indicate end of response body

curl will report Problem (3) in the Chunked-Encoded data error when visiting these servers through COW.

Domains like bbc.co.uk will be recorded as co.uk

One easy solution is to record blocked sites based on host name. But this will generates lots of records in blocked/direct sites list.

I'm still trying to find a good solution for this.

Handle "Redirect" blocking policy

Some networks, e.g. a typical company intranet, will block connections by applying "redirect" policy. They often redirect blocked connections to a warning page or a login page. It means there could exist no reset or timeout for blocked sites. In some situations, we can even get HTTP 200 code when trying to reach a non-existent site.

Furthermore, some DNS pollution/injection techniques enable ISPs to do almost the same things for advisement. An example is that China telecom redirects users to 114 search when they are trying to visit a non-existent or blocked site.

Thanks for your work BTW

Retry request for HTTP CONNECT

Currently working on.

Plan: buffer content from the client. If no response has ever been read from the server, and connection is reset (or timeout?), use socks proxy and re-send buffered content upon connection.

可不可以加入对goagent的支持

对cow的自动路由比较欣赏，goagent的速度非常可观但使用的是手动路由，如果cow能直接支持goagent就可以不用开好几个客户端了

Too many open files results failed client connection

This will happen when using 2 browsers and a few other applications which needs network access. Need to investigate cause and solution.

树莓派安装脚本会报错

pi@raspberrypi ~/mygo/bin $ uname -m
armv6l

直接使用Linux的会报错，不过我自己编译了一个，可以运行，可以打包发给你。

no CRLF after sending r.origReqLine in sendHTTPProxyRequest

att.
Both apache (as parent proxy) and shrpx (from https://github.com/tatsuhiro-t/spdylay) need this to properly parse http request. Without this they will return 400 Bad Request.

youku video can't be visited correctly through cow

Well, I don't visit youku usually. Found this bug after 0.2 is just released.

Twitter for Mac complains too many connections

Not sure if this is caused by COW.

Tweetdeck Chrome App

It seems cow can't find api.tweetdeck.com has been blocked.

Crash when serving multiple users (rarely happen)

Still investigating the root cause.

出错后无法打开url

Chrome for Mac
Shadowsocks

log显示类似这样的emote twitter.com:443 error: Error: This socket is closed. 然后这个url就再也打不开了除非重启chrome或者重启cow

但单独运行 go 是正常的

没有 ~/.cow 文件夹？

按着流程走，安装 Go Installer for Mac 1.0.3 之后，用 sudo go get github.com/cyfdecyf/cow 来安装 COW，然后没有 ~/.cow 文件夹？下载好的原文件都放在 /usr/local/go/src/pkg/github 里面了。如果不用 sudo 的话，就会 permission denied。
