Configure maximum upload file size for CMS 12 and DXP Linux platform

  • Updated

Description

This article explains how to configure max upload file size for CMS 12 web apps. The suggestion below works with Kestrel and DXP Linux platform.

This resolves issues when uploading files larger than 30MB.

 

Steps

1. Configure FormOptions in Startup.cs ConfigureServices method

services.Configure<FormOptions>(x => 
{ 
    x.MultipartBodyLengthLimit = 52428800; 
});

2. Configure maximum request size:

Option 1: Setting max request size for specific requests and paths in Startup.cs Configure method

// Example for /episerver path
app.UseWhen(context => context.Request.Path.StartsWithSegments("/episerver"), appBuilder =>
{
    context.Features.Get<IHttpMaxRequestBodySizeFeature>().MaxRequestBodySize = 52428800;
});

Option 2: Configure globally for all requests in Program.cs

public static IWebHostBuilder CreateWebHostBuilder(string[] args) => 
    WebHost.CreateDefaultBuilder(args) 
    .UseStartup<Startup>() 
    .UseKestrel(options => 
    { 
        options.Limits.MaxRequestBodySize = 52428800; //50MB 
    }); 
}
