Feature Request: Custom HTTP Header Configuration (HSTS, CSP, etc.) for PWA/TWA Optimization

Dear Base44 Support Team,

I'm writing to submit a feature request regarding the ability to configure custom server-side HTTP headers for our hosted applications.

We are currently working on optimizing our GenieChef app for Progressive Web App (PWA) and Trusted Web Activity (TWA) compliance. For these use cases, comprehensive control over HTTP security headers such as Strict-Transport-Security (HSTS), Content-Security-Policy (CSP), X-Frame-Options, Referrer-Policy, and others is crucial.

While we appreciate that some security policies can be partially implemented via <meta> tags in index.html, this is not a full replacement for robust server-side HTTP headers. These headers are essential for enhancing security, mitigating common web vulnerabilities, and ensuring optimal performance and compliance for modern web applications.

We understand that Gzip/Brotli compression is already handled automatically by Cloudflare CDN, which is great. However, the lack of control over other HTTP headers is a significant limitation for developers aiming for high levels of security and PWA/TWA certification.

Could you please consider adding functionality to allow users to configure these server-side HTTP headers for their applications? This would be an incredibly valuable feature for the platform and would greatly benefit many developers.

Thank you for your time and consideration.
