Bias Analysis
Bias Types:
⚠️
windows_first
⚠️
windows_tools
Summary:
The documentation provides configuration examples for multiple origin types, but the IIS (Windows) example is presented before the AKS NGINX (Linux) example. Additionally, the IIS example is detailed and uses Windows-specific configuration (web.config), while there is no equivalent example for generic Linux web servers (e.g., Apache, NGINX outside AKS). This ordering and tool selection may suggest a slight Windows bias.
Recommendations:
- Reorder the example sections so that Linux-based origins (e.g., AKS NGINX, generic NGINX, Apache) are presented before or alongside Windows/IIS examples.
- Add configuration examples for common Linux web servers such as Apache and standalone NGINX (not just AKS ingress), showing how to filter the X-Azure-FDID header.
- Ensure that for every Windows-specific example, there is a Linux equivalent, and that both are equally detailed.
- Explicitly mention cross-platform applicability and provide links or references to Linux documentation where relevant.
