So there are a couple of potential fixes:
- Configure Apache to pass the original HTTP request `Host:` header through to the proxied application. This should then be documented.
- Add a new optional feature to Datasette called something like `base_host` which, if set, is always used in place of the host in `request.url` when constructing new URLs.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",935930820,absolute_url() behind a proxy assembles incorrect http://127.0.0.1:8001/ URLs,
