>             Project: Apache Knox
>          Issue Type: Bug
>          Components: Site
>    Affects Versions: 0.12.0, 0.13.0
>            Reporter: Rick Kellogg

>
> 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.
