Compress data

How can we compress data transmited between TSQLHttpserver and THttpclient?

You can call the RegisterCompress() method on both client and server sides, to use either ZIP (zlib/deflate/gzip), either our SynLZ compression.

Is there any example using RegisterCompress?

In the server I found this method all right, but in TSQLHttpClient I didn't find it.

Can someone help me?

Hi, I'm new in this forum.

How did you solve you problem?
Because I'm having the same problem.

ManUn · 2013-02-16 17:50:52

No...

Ab, Is the data compress by default?

If I use on the server side:

{$define COMPRESSSYNLZ}
  FServer := TSQLHttpServer.Create('8988', DB);

and on the client side:

{$define COMPRESSSYNLZ}
  FHttp := TSQLHttpClient.Create(Servidor, '8988', FModel);

Does this code enable the compression?

The conditional shall be defined at Project level, not before calling Create.

{$define COMPRESSSYNLZ} here won't affect the code in implementation unit.

Do You mean in the source of the project like this?

{$R *.res}
{$define COMPRESSSYNLZ}

begin
  Application.Initialize;
  Application.MainFormOnTaskbar := True;
  Application.CreateForm(TfrmServer, frmServer);
  Application.Run;
end.

No, in the Project Options dialog.

Go to "Project" Menu, then "Options", then "Conditional Defines" (or something similar).

{$define is LOCAL to the current file scope, unless you define it in the project shared options.

If I don't use any Define, does the framework uses COMPRESSDEFLATE as default?

"Use the source, Luke!" and RTFM!

Both server side defines COMPRESSSYNLZ and COMPRESSDEFLATE in unit mORMotHttpServer.
There is no such compiler define in mORMotHttpClient - you have to use the Compressions property, setting e.g. Compression := [hcSynLZ, hcDeflate] to allow both SynLZ and deflate compression algorithms.
Just search for "compression" in mORMotHttpClient and I suspect you will find the info.
