Mike Hagan commented on HTTPCLIENT-1795:
----------------------------------------
Hi,
I started looking this and I have been doing some testing and research.
The problem appears to be with InetAddress.getAllByName and not with the
HttpGet.
Is this correct?
What is the patch that you would like to see?
If you have a particular fix in mind, I will code it, test it and create a
patch.
Thanks,
Mike

> [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:
> {code}
> Request.Get("http://[fe80::221:b7ff:fe8a:57d5%25en4]/";)

> 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.
