Dennis Ju created HTTPCLIENT-1628:
-------------------------------------
Summary: Auth cache can fail when domain name contains uppercase
characters
Key: HTTPCLIENT-1628
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1628
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpAuth
Affects Versions: 4.4 Final
Reporter: Dennis Ju
Priority: Minor
Following the example for using preemptive authentication given in the
documentation
[here|http://hc.apache.org/httpcomponents-client-ga/tutorial/html/authentication.html]
will fail to authenticate if you use uppercase characters in the domain name
like loCalHoST or aPache.org.
This is a new issue with 4.4 because of the new constructor AuthScope(final
HttpHost origin, final String realm, final String schemeName). This constructor
differs from the original constructor AuthScope(final String host, final int
port, final String realm, final String schemeName) where the hostname is
converted to lowercase. The example uses the latter constructor when it creates
the AuthScope, so the hostname is lowercase. When a request is executed,
BasicCredentialsProvider.matchCredentials(...) will try to compare this
lowercase hostname with a newly created AuthScope that doesn't convert to
lowercase, so it always returns false.
The easy fix would be to convert the hostname to lowercase for the first
constructor.
