在不同的网络服务器（nginx、apache、iis 等）中重写响应体的可能性

Question

我正在对常用 Web 服务器之间的差异进行个人研究。当涉及到特定功能时，我正在努力寻找明确的答案，对我来说最重要的是：即时重写响应正文的能力。

场景：web服务器（apache、nginx、iis、varnish、haproxy）部署为反向代理或应用服务器代理（nginx-->passenger为例）。

问题：在哪些网络服务器中以及如何重写响应正文。关于此类操作的简便性和性能的评论或 2 也会有所帮助。

我的研究：

Content rewritting:

Nginx: ngx_http_sub_module
Nginx: LUA body_filter: https://groups.google.com/forum/embed/#!topic/openresty-en/Gj-s_hARc84 
Apache: mod_substitute
Apache: starting from 2.3 LUA can be used as a scripting language (and the response body rewriting with it is possible)
IIS: does not seem top be possible?
Varnish: possible, but hacky: https://github.com/aivarsk/libvmod-rewrite 
HAproxy: not possible, although it might be possible with LUA in the future

还有什么我忘记了吗？谢谢。

Answer 1

最终得到这张表：

**Nginx**: ngx_http_sub_module --> http://p.defau.lt/?A6UukYFKZrYLalJ5KOuTKg 
**Nginx**: Nginx + lua. LUA body_filter --> http://p.defau.lt/?0ZxLWENoEkFIRD17QlEtbQ 
**Apache**: Apache Module mod_substitute --> http://p.defau.lt/?IS8u2mnAQTSHs4qEl_MSFQ 
**Apache**: As of version 2.3 LUA can be used as a scripting language for Apache. Response body rewriting is possible there as well. --> http://p.defau.lt/?tTAqWfA8sezQZkmvI3LnFw 
**Varnish**: Possible, but hacky: https://github.com/aivarsk/libvmod-rewrite 
**HAproxy**: Not possible. Might be possible with LUA in the future
