My name is Johann Rajadurai, and this is my deliverable for Part 1 of the technical project.
This application demonstrates the headers received by the origin server and showcases WAF functionality based on geographic location.

Below are all the HTTP request headers received by the origin server. Each header includes an explanation of its purpose.
| Header Name | Value | Explanation |
|---|---|---|
| x-forwarded-for | 3.15.221.148 | Shows the original IP address of the client, as passed along by proxies. This helps identify the true origin of the request despite going through intermediaries. |
| cf-ray | 92a9e9af4a924402-EWR | Cloudflare's unique request identifier for this transaction. Every request that passes through Cloudflare gets a unique Ray ID that can be used for troubleshooting. |
| accept | */* | Specifies the content types that the client is willing to receive. Allows servers to send the most appropriate format. |
| accept-encoding | gzip, br | Lists the content encodings the client can understand (gzip, deflate, etc.). Helps servers send compressed content to save bandwidth when supported. |
| user-agent | Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; ClaudeBot/1.0; [email protected]) | Information about the client browser, operating system, and device. Helps identify the capabilities of the client. |
| x-forwarded-proto | https | This header provides additional information about the request or response. |
| Host | johannrajadurai.com | Indicates the host name from the request URL. Used to determine which virtual host should handle the request when multiple sites are hosted on the same server. |
| cdn-loop | cloudflare; loops=1 | Indicates that the request may be caught in a CDN loop. Helps prevent infinite loops between CDNs. |
| cf-connecting-ip | 3.15.221.148 | The original IP address of the visitor as detected by Cloudflare. |
| cf-ipcountry | US | This header provides additional information about the request or response. |
| cf-visitor | {"scheme":"https"} | This header provides additional information about the request or response. |
Cloudflare adds several special headers to requests that provide valuable information about the request and visitor. These headers are prefixed with "CF-" and can be used to understand how Cloudflare is processing your traffic.
| Header Name | Value | Explanation |
|---|---|---|
| cf-ray | 92a9e9af4a924402-EWR | Cloudflare's unique request identifier for this transaction. Every request that passes through Cloudflare gets a unique Ray ID that can be used for troubleshooting. |
| cf-connecting-ip | 3.15.221.148 | The original IP address of the visitor as detected by Cloudflare. |
| cf-ipcountry | US | A Cloudflare-specific header. |
| cf-visitor | {"scheme":"https"} | A Cloudflare-specific header. |
