🌐 Web query:

Does ufo hasProtocol function return true for protocol-relative URLs like //example.com by default?

💡 Result:

No. In unjs/ufo, hasProtocol("//example.com") returns false by default; it only returns true for protocol-relative (scheme-relative) URLs if you pass { acceptRelative: true }. [1]

Handle protocol-relative URLs in the src parameter.

The code doesn't account for protocol-relative URLs (e.g., //cdn.example.com/image.jpg). Since hasProtocol returns false for these by default, they would be incorrectly joined with baseURL, producing malformed results like https://mysite.com//cdn.example.com/image.jpg.

Use hasProtocol(src, { acceptRelative: true }) to properly detect protocol-relative URLs as absolute:

Fix for protocol-relative URL handling 
-    const url = operations ? joinURL(baseURL, 'cdn-cgi/image', operations, src) : hasProtocol(src) ? src : joinURL(baseURL, src)
+    const url = operations ? joinURL(baseURL, 'cdn-cgi/image', operations, src) : hasProtocol(src, { acceptRelative: true }) ? src : joinURL(baseURL, src)

Alternatively, the nested ternary could be rewritten as an if-else block for improved readability.

In `@src/runtime/providers/cloudflare.ts` at line 49, The URL assembly incorrectly
treats protocol-relative sources as relative because hasProtocol(src) is used;
update the check to hasProtocol(src, { acceptRelative: true }) (or refactor the
ternary into an if/else) so protocol-relative URLs (e.g., //cdn.example.com/...)
are treated as absolute and not joined with baseURL; adjust the expression that
sets url (which uses joinURL, baseURL, operations, src) to use this updated
hasProtocol call and preserve the existing logic for operations and normal
relative paths.
