Write another 'advanced' onion service page: how to scale your onion
We should have another advanced onion service doc page, where we talk about onionbalance, and we talk about setting up a reverse proxy and give warnings about only proxying to https, and we talk about how the current onion service protocol has DoS vulnerabilities and sketch out the future solutions we're imagining.
See also tpo/web/community#114 (closed) which is onionbalance-specific.
