Subject [jira] [Commented] (CONNECTORS-1564) Support preemptive authentication to Solr connector
Date Mon, 25 Feb 2019 15:22:00 GMT

    [ https://issues.apache.org/jira/browse/CONNECTORS-1564?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16776993#comment-16776993

Erlend Garåsen commented on CONNECTORS-1564:
--------------------------------------------

[~michael-o], I will create a ticket this afternoon. I have added more code to my small application
which will be sent along with the ticket. Now I have SolrJ code which does not show any expect
header and native HttpClient code which actually works as expected. The following sample is
a simplified version of your code where the Expect: 100-continue shows up in the logs:
{code:java}
HttpPost httpPost = new HttpPost(baseUrl);
HttpEntity entity = new InputStreamEntity(new ByteArrayInputStream("test".getBytes()));
httpPost.setEntity(entity);
httpClient.execute(httpPost);{code}
{noformat}
DEBUG 25.02.2019 16:06:35:567 (LoggingManagedHttpClientConnection.java:onRequestSubmitted:136)
- http-outgoing-0 >> Expect: 100-continue{noformat}

> 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.
