> [RFC 6874|https://tools.ietf.org/html/rfc6874] states that, when constructing a URL with
an LLv6 literal, the {{%}} sign that prefixes the ZoneID must be quoted as {{%25}}. E.g.,
the LLv6 address 
> {{fe80::221:b7ff:fe8a:57d5%en4}} should be specified as {{scheme://[fe80::221:b7ff:fe8a:57d5%25en4]/...}}
in a URL.
> httpclient does not seem to support quoted host literals:
> Example:

>                 .socketTimeout(1000)
>                 .execute().returnContent().asString();
> {code}
> results in

> It appears that httpclient directly passes the host literal {{[fe80::221:b7ff:fe8a:57d5%25en4]}}
to the Java standard method {{InetAddress.getAllByName(host)}}, which does not support the
URL quoting that RFC 6874 prescribes.
