[jira] [Updated] (HTTPCLIENT-1795) Http Client does not support
RFC-compliant quoted IPv6 Link-Local host literals
[ https://issues.apache.org/jira/browse/HTTPCLIENT-1795?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andreas Wundsam updated HTTPCLIENT-1795:
----------------------------------------
Description:
[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]/")
.connectTimeout(1000)
.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.
