Description
Cloudflare Pages’ _headers file should support multiline headers that are joined by “;” instead of “,”
Benefit
_headers files have nice support for multiline headers that are joined by commas. For example,
/*
Feature-Policy: document-domain 'none'
Feature-Policy: layout-animations 'none'
turns into Feature-Policy: document-domain 'none', layout-animations 'none'.
However, some headers are joined by semicolons instead, such as Content-Security-Policy.
/*
Content-Security-Policy: frame-ancestors 'self';
Content-Security-Policy: media-src 'self';
turns into Content-Security-Policy: frame-ancestors 'self';, media-src 'self';. An extra comma is inserted.
For what it’s worth, Netlify supports joining with semicolons using the above syntax.
