How to clear header?

[sodlf159]

try
TempHeaderMap := TCefStringMultimapOwn.Create;
request.GetHeaderMap(TempHeaderMap);
TempHeaderMap.Append('Accept-Encoding', 'gzip, deflate');
TempHeaderMap.Append('TEST', '1');
request.SetHeaderMap(TempHeaderMap);
finally
TempHeaderMap := nil;
end;

The addition works well, but

I don't know how to delete a specific header name.

TempHeaderMap.Append('TEST', '1'); << Clear

Create a new TCefStringMultimapOwn, copy the rest of the headers, Append your own header and then call the SetHeaderMap method with the new TCefStringMultimapOwn instance.

See this example :

Thank you. I solved it.
Also Do Not Track (DNT)
DNT = 1
What is the way to get rid of this?

Set TChromiumCore.DoNotTrack to False.
