I'm sniffing a.NET Framework 4.8 application in order to obtain http web request/response data which is in the http body. I followed the steps described here to export HTTP objects. It says there that the content will be uncompressed when saved. But this is not valid in my case.

The app uses System.IO.Compression.DeflateStream class to compress/uncompress. Is there a way to do it with wireshark without writing any script/program to uncompress the saved file.

POST /P.svc HTTP/1.1
Cache-Control: no-cache, max-age=0
Accept-Encoding: gzip, deflate
Content-Type: application/x-deflate
Content-Length: 990

DeflateStream Class

Is the uncompressed data available as a tab in the Packet Bytes? Is it only the export that's not working?
