> When using the Java SOLRJ HttpSolrClient, any operation that relies upon a POST HTTP
operation fails authentication when proxied via Knox.  This is because the SOLRJ API only
supports traditional challenge/response basic authentication.  For any update style operation
the SOLRJ client refuses to retry the operation as it might lead to duplicate data, etc. 
If this were a GET operation, it would retry the operation and include the appropriate authentication
header.
> Therefore preemptive authentication must be used for updates to succeed.  Unfortunately,
the Apache HttpClient construction is hidden from the client in the form of the HttpSolrClient.Builder
class.
