ASP.NET Response Compression

 

//public void ConfigureServices(IServiceCollection services)

services.AddResponseCompression(options =>

{

    options.MimeTypes = new[] { "application/json" };

    //options.EnableForHttps = true;

});

// ...

// public void Configure(IApplicationBuilder app, IWebHostEnvironment env, IServiceScopeFactory scopeFactory)

app.UseResponseCompression();

Beware of the security issues when using EnableForHttps .
