Bug with relative Location header

[jcamiel]

Given the following Hurl file:

redirect.hurl:

# Absolute redirects
GET http://localhost:8000/redirect
HTTP/1.0 302
Location: http://localhost:8000/redirected

GET http://localhost:8000/redirected
HTTP/1.0 200


GET http://localhost:8000/redirect
[Options]
location: true

HTTP/1.0 200
```Redirected```

# Relative redirects
GET http://localhost:8000/relative-redirect
HTTP/1.0 302
Location: /redirected

GET http://localhost:8000/relative-redirect
[Options]
location: true

HTTP/1.0 200
```Redirected```

redirect.py:

from app import app
from flask import redirect, Response


@app.route("/redirect")
def redirectme():
    return redirect("http://localhost:8000/redirected")

@app.route("/relative-redirect")
def relative_redirectme():
    response = Response(status=302)
    response.headers['Location'] = '/redirected'
    response.autocorrect_location_header = False
    return response


@app.route("/redirected")
def redirected():
    return "Redirected"

Hurl is in error:

error: HTTP connection
  --> integration/tests_ok/redirect.hurl:22:5
   |
22 | GET http://localhost:8000/relative-redirect
   |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ (3) URL using bad/illegal format or missing URL
   |

Whereas curl command is ok:

$ curl 'http://localhost:8000/relative-redirect' -L
Redirected

It seems like we have issues with relative Location header. curl seems ok with it and on MDN location can be relative:

A relative (to the request URL) or absolute URL.
