Subject [jira] [Commented] (CONNECTORS-1564) Support preemptive authentication to Solr connector
Date Thu, 17 Jan 2019 19:39:00 GMT

    [ https://issues.apache.org/jira/browse/CONNECTORS-1564?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16745422#comment-16745422

Karl Wright commented on CONNECTORS-1564:
-----------------------------------------

[~michael-o] thanks for trying this.

I await Erlend's more precise description of his setup.  We are in fact setting up the HttpClientBuilder
exactly as you recommend:

{code}
    RequestConfig.Builder requestBuilder = RequestConfig.custom()
      .setCircularRedirectsAllowed(true)
      .setSocketTimeout(socketTimeout)
      .setExpectContinueEnabled(true)
      .setConnectTimeout(connectionTimeout)
      .setConnectionRequestTimeout(socketTimeout);

    HttpClientBuilder clientBuilder = HttpClients.custom()
      .setConnectionManager(connectionManager)
      .disableAutomaticRetries()
      .setDefaultRequestConfig(requestBuilder.build())
      .setRedirectStrategy(new LaxRedirectStrategy())
      .setRequestExecutor(new HttpRequestExecutor(socketTimeout));
{code}

> We should post preemptively in case the Solr server requires basic authentication. This
will make the communication between ManifoldCF and Solr much more effective instead of the
following:
>  * Send a HTTP POST request to Solr
>  * Solr sends a 401 response
>  * Send the same request, but with a "{{Authorization: Basic}}" header
> With preemptive authentication, we can send the header in the first request.
