Decoding GZIP web response

[ststreck]

Hi Tim,
I really apreciate your effort in keeping Excel-Rest up-to-date.
Hope that my issue is a simple one.

I use a Web-Service returning a JSON String, but for performance it is GZIP encoded.
So I add a Header:
Request.AddHeader "Accept-Encoding", "gzip, deflate"

This works fine, so I get an gzip encoded response.
Now Im searching for a way how to decode this before it is handed over to the parser.

Regards
Stephan

@ststreck I've looked into gzip decoding, but that is quite a task and I couldn't find a cross-platform approach. This can be added with a custom converter (with your own gzip decoder) in v4.0.0

' GzipConverter.bas
Public Function ConvertToGzip(Value As Variant) As String
    ' (Not implemented)
End Function
Public Function ParseGzip(Value As String) As Object
    ' Parse GZIP...
End Function

' Before request
WebHelpers.RegisterConverter "gzip", "your-response-type", _
  "GzipConverter.ConvertToGzip", "GzipConverter.ParseGzip"

' With request
Request.CustomResponseFormat = "gzip"
