Erlend Garåsen commented on CONNECTORS-1564:
--------------------------------------------
[[email protected]] and [~michael-o]: We are getting closer. I can confirm
that expect 100-continue works with Apache 2.5. I included the header in
ModifiedHttpSolrClient.java this way:
{{Override}}
{{protected NamedList<Object> executeMethod(final HttpRequestBase method, final
ResponseParser parser,}}
{{ final boolean isV2Api) throws SolrServerException {}}
{{ method.addHeader("Expect", "100-continue");}}
{{ return super.executeMethod(method, parser, isV2Api);}}
{{}}}
Now I can see the following in my logs:
{{DEBUG 2019-01-30T13:44:00,729 (Thread-2237) - http-outgoing-1 >> "Expect:
100-continue[\r][\n]"}}
Maybe we have a bug in ModifiedHttpSolrClient.java. I wasn't able to log
anything useful from httpClientBuilder. Anyway, the setup code seems
reasonable. It's almost the same I have done in another Solr connector I have
written.

> 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.
