How to make "URL" case insensitive (globally)?

[4n1qz5skwv]

from litestar import Litestar, get


@get("/AbC")
def hello_world() -> dict[str, str]:
    return {"hello": "world"}


app = Litestar(route_handlers=[hello_world])
if __name__ == '__main__':
    import uvicorn

    uvicorn.run('0:app')

You can't. Our routing is not regex based but trie based. This is a limitation of the design.

URLs should generally be treated as case-sensitive, since there are no guarantees about case-insensitivity.

Technically speaking the scheme and host part are case-insensitive, while other parts like path and query may be case-sensitive

Case-insensitive host: https://www.rfc-editor.org/rfc/rfc3986#section-3.2.2
No mention of case (in)sensitivity for path: https://www.rfc-editor.org/rfc/rfc3986#section-3.3
