637395097,MDU6SXNzdWU2MzczOTUwOTc=,838,Incorrect URLs when served behind a proxy with base_url set,79913,closed,0,,6026070,14,2020-06-11T23:58:55Z,2021-11-20T19:35:48Z,2021-11-20T19:35:48Z,NONE,,"I'm running `datasette serve --config base_url:/foo/ …`, proxying to it with this Apache config:

        ProxyPass /foo/ http://localhost:8001/ 
        ProxyPassReverse /foo/ http://localhost:8001/ 

and then accessing it via `https://example.com/foo/`.

Although many of the URLs in the pages are correct (presumably because they either use absolute paths which include `base_url` or relative paths), the faceting and pagination links still use fully-qualified URLs pointing at `http://localhost:8001`.

I looked into this a little in the source code, and it seems to be an issue anywhere `request.url` or `request.path` is used, as these contain the values for the request between the frontend (Apache) and backend (Datasette) server. Those properties are primarily used via the `path_with_…` family of utility functions and the `Datasette.absolute_url` method.",107914493,issue,,,"{""url"": ""https://api.github.com/repos/simonw/datasette/issues/838/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed

This could be user error in how I've set up the reverse proxy!

I started datasette like so:
`docker run -d -p 8001:8001 -v `pwd`:/mnt datasetteproject/datasette datasette -p 8001 -h 0.0.0.0 /mnt/corpora-metadata.db --config sql_time_limit_ms:60000 --config base_url:/datasette/`

I then reverse proxied like so:

  ProxyPreserveHost On
  ProxyPass /datasette http://x.y.z.q:xxxx
  ProxyPassReverse /datasette http://x.y.z.q:xxx

Regular sql works perfectly:

I've been playing with Datasette behind Nginx (awesome tool, thanks !). It seems some URLs are OK but some aren't. For instance in https://github.com/simonw/datasette/blob/master/datasette/templates/query.html#L61 it seems that `url_csv` includes a `/` prefix, resulting in the `base_url` not beeing honored.

Actually here, it seems that dropping the prefix `/` to make the link relative is enough (so it may not be strictly related to `base_url`).

Additional information:

```
datasette, version 0.45+0.gf1f581b.dirty
```

Relevant Nginx configuration (note that all the trailing slashes have some effect):

```
  location /datasette/ {
    proxy_pass http://127.0.0.1:9001/;
    proxy_set_header Host $host;
  }
```

Relelvant Datasette configuration (slashes matter too):

```
  --config base_url:/datasette/
```",107914493,issue,,,"{""url"": ""https://api.github.com/repos/simonw/datasette/issues/900/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed
