How to Configure Windows Sandbox Local Traefik RateLimit Middleware via XML in Windows 11

Testing defensive API rate-limiting rules against traffic spikes demands an isolated, disposable sandbox environment. Windows Sandbox on Windows 11 enables engineers to launch a completely independent container, install Traefik edge proxy, and test rate-limiting thresholds without exposing internal network boundaries or persisting test artifacts.

Defining the Windows Sandbox XML Specification

Save the following XML payload as TraefikRateLimitSandbox.wsb on your Windows 11 system:

<Configuration>
  <VGpu>Default</VGpu>
  <Networking>Default</Networking>
  <MappedFolders>
    <MappedFolder>
      <HostFolder>C:\TraefikRateLimitLab</HostFolder>
      <SandboxFolder>C:\TraefikRateLimitLab</SandboxFolder>
      <ReadOnly>true</ReadOnly>
    </MappedFolder>
  </MappedFolders>
  <LogonCommand>
    <Command>powershell.exe -ExecutionPolicy Bypass -NoExit -File C:\TraefikRateLimitLab\setup-ratelimit.ps1</Command>
  </LogonCommand>
</Configuration>

Authoring the Rate-Limiting Automation Script

Create the PowerShell bootstrapper at C:TraefikRateLimitLabsetup-ratelimit.ps1:

Write-Host "Configuring Traefik Rate-Limit Sandbox..." -ForegroundColor Cyan

$Target = "C:Traefik"
New-Item -ItemType Directory -Force -Path $Target | Out-Null

$TraefikZip = "https://github.com/traefik/traefik/releases/download/v3.0.0/traefik_v3.0.0_windows_amd64.zip"
Invoke-WebRequest -Uri $TraefikZip -OutFile "$Target	raefik.zip"
Expand-Archive -Path "$Target	raefik.zip" -DestinationPath $Target -Force

$Config = @"
http:
  middlewares:
    api-ratelimit:
      rateLimit:
        average: 10
        burst: 20
        period: "1m"
  routers:
    mock-router:
      rule: "PathPrefix(`/api`)"
      middlewares:
        - "api-ratelimit"
      service: "noop-service"
  services:
    noop-service:
      loadBalancer:
        servers:
          - url: "http://127.0.0.1:8080"
"@

Set-Content -Path "$Targetdynamic_conf.yml" -Value $Config
Write-Host "Traefik RateLimit Middleware Ready." -ForegroundColor Green

Executing Load Tests Inside the Container

Launch the sandbox configuration and run burst HTTP requests via PowerShell to verify that requests exceeding the burst threshold return HTTP 429 Too Many Requests. Closing the sandbox instantly clears all generated logs and binary files cleanly.
