Is there any binary tool or implementation source code example, which can decode and encode content in "xpress" content-encoding?
The only thing I could find, is the [MS-XCA]: Xpress Compression Algorithm verbal description.
It is required to understand the content of server responses like the following:
HTTP/1.1 200 OK
Cache-Control: private
Content-Type: application/soap+xml; charset=utf-8
Content-Encoding: xpress
Vary: Accept-Encoding
Server: Microsoft-IIS/10.0
X-Powered-By: ASP.NET
Date: Wed, 13 Sep 2017 10:56:16 GMT
Content-Length: 1003
<!-- Response in xpress encoding -->
