uWSGI Router Header Injection for Django/Flask Accessibility

uWSGI Router Header Injection for Django/Flask Accessibility

Goal: Configure uWSGI so that a single server‑level rule set injects accessibility‑related HTTP headers (e.g., CSP, X‑Content‑Type‑Options, ARIA‑role hints) into responses from multiple Django or Flask applications without modifying the WSGI code.

• Which router directives allow selective injection of Content‑Security‑Policy and X‑Content‑Type‑Options headers while preventing duplication with app‑level headers?
• How can ARIA compliance attributes be exposed via uWSGI response headers at the server level without app code changes?
• What security implications arise from broad header injection in a multi‑tenant uWSGI Emperor deployment, and how can they be mitigated?
