Rate Limiting (Wall) Command

Implement IP-based rate limiting using AspNetCoreRateLimit and Redis distributed cache in the ABP Framework AuthServer.

Arguments: $ARGUMENTS

Pre-flight

Project: !basename $(pwd) AuthServer Module: !find api/src -maxdepth 1 -type d -name "*AuthServer" 2>/dev/null | head -1

Required context:

• Read CLAUDE.md for project conventions
• Read docs/architecture/README.md for project paths

Overview

This command implements distributed rate limiting to protect your AuthServer from abuse and DoS attacks by:

• Limiting requests per IP address
• Configuring endpoint-specific limits
• Using Redis for distributed caching across multiple instances
• Providing 429 (Too Many Requests) responses when limits are exceeded

Execution

1. Verify AuthServer exists

# Find AuthServer project
AUTH_SERVER=$(find api/src -maxdepth 1 -type d -name "*AuthServer" 2>/dev/null | head -1)

if [ -z "$AUTH_SERVER" ]; then
  echo "❌ ERROR: AuthServer project not found in api/src/"
  echo "Expected: api/src/{ProjectName}.AuthServer/"
  exit 1
fi

echo "✓ Found AuthServer: $AUTH_SERVER"

2. Install required NuGet packages

# Navigate to AuthServer project
cd "$AUTH_SERVER"

# Install AspNetCoreRateLimit
dotnet add package AspNetCoreRateLimit

# Install Redis support
dotnet add package AspNetCoreRateLimit.Redis

# Install StackExchange.Redis if not already present
dotnet add package StackExchange.Redis

cd ../../..

3. Configure HostModule

File: {AuthServer}/ClinicManagementSystemAuthServerModule.cs (or similar)

Add using statements at the top of the file:

using AspNetCoreRateLimit;
using StackExchange.Redis;
