>             Project: Solr
>          Issue Type: Improvement
>          Components: clients - java
>    Affects Versions: 4.0-ALPHA
>            Reporter: Martin Grotzke
>            Priority: Minor
>         Attachments: SOLR-3318.git.patch
> For a user query we make several solr queries that differ only slightly and 
> therefore should use/reuse objects cached from the first query (we're using a 
> custom request handler and custom caches).
> Thus such subsequent queries should hit the same solr server.
> The implemented solution looks like this:
> * The client obtains a live SolrServer from LBHttpSolrServer
> * The client provides this SolrServer as preferred server for a query
> * If the preferred server is no longer alive the request is retried on 
> another live server
> * Everything else follows the existing logic:
> ** After live servers are exhausted, any servers previously marked as dead 
> will be tried before failing the request
> ** If no live servers are found a SolrServerException is thrown
> The implementation is also [on 
> github|https://github.com/magro/lucene-solr/commit/a75aef3d].
