gzip压缩无法与IIS 8.5一起使用 [英] gzip compression not working with IIS 8.5

问题描述

我有一个运行IIS的Server 2012 R2。我已经尝试为在该盒子上运行的几个站点启用压缩，但我无法弄清楚它为什么不起作用。我的请求标头都显示了accept-encoding，但响应标头始终是Transfer-Encoding：chunked和Vary：Accept-Encoding。已执行以下步骤以尝试使gzip压缩工作：

I have a Server 2012 R2 box running IIS. I've tried enabling compression for several sites running on that box, but I can't figure out why it won't work. My request headers all show accept-encoding, but the response headers are always Transfer-Encoding:chunked and Vary:Accept-Encoding. The following steps have been performed to try to get gzip compression working:

1. 已在每个站点和计算机上启用动态和静态压缩级别


2. 两种压缩方法都是从服务器管理器安装的。


3. Httpcompression和urlcompression节点已手动添加到web.configs


4. 为压缩定义Mime类型


5. frequentHitThreshold已设置为1，因此所有内容应在首次尝试访问后进行压缩

1. Dynamic and Static compression have been enabled on each site and at the machine level
2. Both compression methods are installed from Server Manager
3. Httpcompression and urlcompression nodes have been manually added to web.configs
4. Mime types are defined for compression
5. frequentHitThreshold has been set to 1, so all content should be compressed after the first attempt to access it

已经进行了跟踪以了解为什么没有进行压缩。我唯一的信息是代码DYNAMIC_COMPRESSION_NOT_SUCCESS，原因为1.

A trace has been done to see why compression isn't occurring. The only information I have is the code DYNAMIC_COMPRESSION_NOT_SUCCESS with a reason of 1.

以下是标题：

可以执行哪些其他步骤来使压缩起作用？

What other steps can be performed to get compression to work?

推荐答案

压缩工作正常，但ESET Antivirus正在监控网络流量。这修改了响应，我没有按预期获得gzip内容编码。禁用ESET并再次测试表明压缩正在运行。

Compression was working, but ESET Antivirus was doing its job of monitoring web traffic. This modified the response and I didn't get gzip content encoding as expected. Disabling ESET and testing again showed that compression was functioning.
