Handle SSL Termination when Validating Twilio Webhook Requests in Node.js

SSL termination is a process where SSL/TLS encrypted traffic is decrypted at a designated endpoint before being forwarded to backend servers. This technique helps in handling secure HTTPS connections efficiently and balancing traffic among multiple servers. However, it may introduce unencrypted traffic within the internal network between the termination point and the backend servers. To handle SSL termination when validating Twilio webhook requests in Node.js, developers need to reconstruct the original URL that Twilio used by checking the x-forwarded-proto header. This ensures that during Twilio's webhook validation, the signature is compared against the correct URL, accounting for any SSL termination or proxy layers.
