Error on batched queries

Google Fonts supports batching multiple fonts together in a single stylesheet, which will yield url's like: https://fonts.googleapis.com/css2?family=Atkinson+Hyperlegible+Next:ital,wght@0,200..800;1,200..800&family=Fira+Code:wght@300..700&family=Lato:ital,wght@0,100;0,300;0,400;0,700;0,900;1,100;1,300;1,400;1,700;1,900&display=swap

However, the proxy will try to make this into a base64 string and fail, because it'll be too long for the file system to support.
