1811824307,I_kwDOBm6k_c5r_j6z,2105,When reverse proxying datasette with nginx an URL element gets erronously added,2235371,open,0,,,3,2023-07-19T12:16:53Z,2023-07-21T21:17:09Z,,NONE,,"I use this nginx config:
```
    location /datasette-llm {
      return 302 /datasette-llm/;
    }

    location /datasette-llm/ {
      proxy_set_header Upgrade           $http_upgrade;
      proxy_set_header Connection        ""Upgrade"";
      proxy_http_version 1.1;
      proxy_set_header X-Real-IP         $remote_addr;
      proxy_set_header X-Forwarded-For   $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Proto https;
      proxy_set_header X-Forwarded-Host  $http_host;
      proxy_set_header Host              $host;
      proxy_max_temp_file_size           0;
      proxy_pass                         http://127.0.0.1:8001/datasette-llm/;
      proxy_redirect                     http:// https://;
      proxy_buffering off;
      proxy_request_buffering off;
      proxy_set_header Origin            '';
      client_max_body_size 0;
      auth_basic                         ""datasette-llm"";
      auth_basic_user_file               /etc/nginx/custom-userdb;
    }
```
Then I start datasette with this command:
```
datasette serve --setting base_url /datasette-llm/ $(llm logs path)
```
Everything else works right, except the links in ""This data as json, CSV"".
They get an extra URL element ""datasette-llm"" like this:

https://192.168.1.3:5432/datasette-llm/datasette-llm/logs.json?sql=select+*+from+_llm_migrations

https://192.168.1.3:5432/datasette-llm/datasette-llm/logs.csv?sql=select+*+from+_llm_migrations&_size=max

When I remove that extra ""datasette-llm"" from the URL, those links work too.",107914493,issue,,,"{""url"": ""https://api.github.com/repos/simonw/datasette/issues/2105/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,
