Jan Høydahl created SOLR-14250:
----------------------------------
Summary: Solr tries to read request body after error response is
sent
Key: SOLR-14250
URL: https://issues.apache.org/jira/browse/SOLR-14250
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Jan Høydahl
If a client sends a {{HTTP POST}} request with header {{Expect: 100-continue}}
the normal flow is for Solr (Jetty) to first respond with a {{HTTP 100
continue}} response, then the client will send the body which will be processed
and then a final response is sent by Solr.
However, if such a request leads to an error (e.g. 404 or 401), then Solr will
skip the 100 response and instead send the error response directly. The very
last ation of {{SolrDispatchFilter#doFilter}} is to call
{{consumeInputFully()}}. However, this should not be done in case an error
response has already been sent, else you'll provoke an exception in Jetty's
HTTP lib:
