Does this request work

I was just trying some random request on the refserver

`https://htsget.ga4gh.org/variants/giab.NA12878?referenceName=1&start=132323&end=133333`

And I got below in the response.

Is this the URL we should expect? The URL is `https://htsget.ga4gh.org/variants/data/giab.NA12878?end=133333\u0026referenceName=1\u0026start=132323`

Best,

```
{"htsget":{"format":"VCF","urls":[{"url":"https://htsget.ga4gh.org/variants/data/giab.NA12878","headers":{"HtsgetBlockClass":"header","HtsgetCurrentBlock":"0","HtsgetTotalBlocks":"2"},"class":"header"},{"url":"https://htsget.ga4gh.org/variants/data/giab.NA12878?end=133333\u0026referenceName=1\u0026start=132323","headers":{"HtsgetCurrentBlock":"1","HtsgetTotalBlocks":"2"},"class":"body"}]}}
```

Start by reproducing the request against the refserver URL shown in the issue and compare the returned URLs with the HTSget API specification. Trace how the response constructs the two data URLs; done means the expected URL behavior is confirmed or a precise, tested correction is identified.
