GZip Compression on HTTP Server

[jorgen]

I now use
unit rtcZLib;

like

 TRtcDataServer(Sender).Response['Content-Encoding'] := 'deflate';
 WriteEx(ZCompress_Ex(RtcStringToBytes(AValue), zcDefault)); // using default compression strength

This works on IOS, but not on Android

It seems to be better to use GZip


How can I best add GZip compression?
Do you have any samples on that?

You won't be able to do what you want with functions included in the rtcZLib unit included in the RTC SDK, because that unit only includes raw compression and decompression functions required for RTC remote functions. But, you might be able to find what you need in the zLib unit from Delphi.

This worked

  with TRtcDataServer(Sender) do
  begin
    TRtcDataServer(Sender).Response.ContentType := 'application/json';

    if Request.Complete then
    begin

TRtcDataServer(Sender).Response['Content-Encoding'] := 'gzip';
Write(GZCompressStr(AValue));

     end;

    end;



Is this the best solution?

Well ... you've said that it works and it's quite simple, which makes it a good solution in my book

PS. You can move all the code for preparation of the response headers into the "if Request.Complete then" block, unless you want it to be executed for every chunk of the request data received.
