即使日志显示它正常工作，IIS压缩也会在响应中缺少内容编码(IIS Compression missing content-encoding in response even though logs show it working)

我想用gzip压缩来提供.js文件

我正在使用IIS 7.5并启用了动态和静态内容压缩。

在IIS日志中，我可以看到以下日志，它显示它似乎正在工作，因为它在“GENERAL_RESPONSE_HEADERS”事件中显示“Content-Encoding：gzip”

<Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="WWW Server" Guid="{3A2A4E84-4C21-4981-AE10-3FDA0D9B0F83}"/> <EventID>0</EventID> <Version>1</Version> <Level>4</Level> <Opcode>47</Opcode> <Keywords>0x0</Keywords> <TimeCreated SystemTime="2017-03-29T23:40:41.555Z"/> <Correlation ActivityID="{8000000D-0003-FA00-B63F-84710C7967BB}"/> <Execution ProcessID="12296" ThreadID="13868"/> <Computer>AUD64909W0</Computer> </System> <EventData> <Data Name="ContextId">{8000000D-0003-FA00-B63F-84710C7967BB}</Data> <Data Name="Headers">Transfer-Encoding: chunked Content-Type: application/javascript Content-Encoding: gzip Last-Modified: Wed, 29 Mar 2017 20:33:32 GMT Accept-Ranges: bytes ETag: "d6af72bbcba8d21:0" Vary: Accept-Encoding Server: Microsoft-IIS/10.0 X-Powered-By: ASP.NET </Data> </EventData> <RenderingInfo Culture="en-NZ"> <Opcode>GENERAL_RESPONSE_HEADERS</Opcode> </RenderingInfo> <ExtendedTracingInfo xmlns="http://schemas.microsoft.com/win/2004/08/events/trace"> <EventGuid>{D42CF7EF-DE92-473E-8B6C-621EA663113A}</EventGuid> </ExtendedTracingInfo> </Event>

但是，在Fiddler或Chrome开发工具中查看时，响应标头未显示Content-Encoding。

HTTP/1.1 200 OK Transfer-Encoding: chunked Content-Type: application/javascript Last-Modified: Wed, 29 Mar 2017 20:33:32 GMT Accept-Ranges: bytes ETag: "d6af72bbcba8d21:0" Vary: Accept-Encoding Server: Microsoft-IIS/10.0 X-Powered-By: ASP.NET Date: Thu, 30 Mar 2017 00:57:20 GMT

任何想法为什么这不起作用

I'm wanting to serve a .js file with gzip compression

I'm using IIS 7.5 and have dynamic and static content compression enabled.

In the IIS logs I can see the following log which shows that it appears to be working as it shows "Content-Encoding: gzip" in the "GENERAL_RESPONSE_HEADERS" event

<Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="WWW Server" Guid="{3A2A4E84-4C21-4981-AE10-3FDA0D9B0F83}"/> <EventID>0</EventID> <Version>1</Version> <Level>4</Level> <Opcode>47</Opcode> <Keywords>0x0</Keywords> <TimeCreated SystemTime="2017-03-29T23:40:41.555Z"/> <Correlation ActivityID="{8000000D-0003-FA00-B63F-84710C7967BB}"/> <Execution ProcessID="12296" ThreadID="13868"/> <Computer>AUD64909W0</Computer> </System> <EventData> <Data Name="ContextId">{8000000D-0003-FA00-B63F-84710C7967BB}</Data> <Data Name="Headers">Transfer-Encoding: chunked Content-Type: application/javascript Content-Encoding: gzip Last-Modified: Wed, 29 Mar 2017 20:33:32 GMT Accept-Ranges: bytes ETag: "d6af72bbcba8d21:0" Vary: Accept-Encoding Server: Microsoft-IIS/10.0 X-Powered-By: ASP.NET </Data> </EventData> <RenderingInfo Culture="en-NZ"> <Opcode>GENERAL_RESPONSE_HEADERS</Opcode> </RenderingInfo> <ExtendedTracingInfo xmlns="http://schemas.microsoft.com/win/2004/08/events/trace"> <EventGuid>{D42CF7EF-DE92-473E-8B6C-621EA663113A}</EventGuid> </ExtendedTracingInfo> </Event>

However the response headers when viewed in Fiddler or Chrome dev tools are not showing Content-Encoding.

HTTP/1.1 200 OK Transfer-Encoding: chunked Content-Type: application/javascript Last-Modified: Wed, 29 Mar 2017 20:33:32 GMT Accept-Ranges: bytes ETag: "d6af72bbcba8d21:0" Vary: Accept-Encoding Server: Microsoft-IIS/10.0 X-Powered-By: ASP.NET Date: Thu, 30 Mar 2017 00:57:20 GMT

Any ideas why this ain't working
