GZip压缩无法在Internet Explorer 11中运行，但在Chrome和Firefox中运行良好

Question

Co's,

I enabled GZip compression in my Spring Boot Embedded Tomcat using CompressingFilter ( https://github.com/ziplet/ziplet ) and FilterRegistrationBean from Spring.

It is working fine in Chrome & Firefox .

• I am getting Content-Encoding = gzip in response headers
• Transferred JSON data size is reduced from 6.5MB to 1.2 MB - Great :-)

But, the same code is NOT working in Internet Explorer 11.0.9600.18097.

In Internet Explorer,

• Content-Encoding = gzip is missing in response headers
• Transferred JSON data size is still 6.5MB only.

I have pasted my headers ( IE11 ) below.

Could anyone help me to figure out this issue?

Update: Please find Chrome Headers below.

Answer 1

Internet Explorer's decompression logic happens at a level below the Developer Tools, so you may not see a Content-Encoding in the Developer Tools. You should consider using Fiddler to see what's actually on the wire.

Please have a look at the link . It was filed as an issue, but microsoft decided for whatever reason not to fix on IE11. They fixed it in the new Edge browser.

Please take a look at the comments in the link provided.
