Enhanced OneClickCDN

An improved and modernized version of OneClickCDN, providing enterprise-grade CDN capabilities with advanced monitoring, security, and automation features. This script allows you to quickly set up and manage CDN nodes using Apache Traffic Server.

This script creates CDN nodes that function similarly to Cloudflare's servers:

• Basic SSL management
• Limited error handling
• Manual monitoring

The enhanced version introduces:

• Robust Error Handling

  • Comprehensive error trapping
  • Detailed logging system
  • Graceful failure handling
