: Some extra information. If I use curl and force it to use HTTP 1.0, it is more : visible that Solr doesn't allow persistent connections:
a) solr has nothing to do with it, it's entirely something under the control of jetty & the client. b) i think you are introducing confusion by trying to force an HTTP/1.0 connection -- Jetty supports Keep-Alive for HTTP/1.1, but maybe not for HTTP/1.0 ? If you use curl to request multiple URLs and just let curl & jetty do their normal behavior (w/o trying to bypass anything or manually add headers) you can see that keep-alive is in fact working... $ curl -v --keepalive 'http://localhost:8983/solr/select?q=*:*' 'http://localhost:8983/solr/select?q=foo' * About to connect() to localhost port 8983 (#0) * Trying 127.0.0.1... connected > GET /solr/select?q=*:* HTTP/1.1 > User-Agent: curl/7.22.0 (x86_64-pc-linux-gnu) libcurl/7.22.0 OpenSSL/1.0.1 > zlib/1.2.3.4 libidn/1.23 librtmp/2.3 > Host: localhost:8983 > Accept: */* > < HTTP/1.1 200 OK < Content-Type: application/xml; charset=UTF-8 < Transfer-Encoding: chunked < <?xml version="1.0" encoding="UTF-8"?> <response> <lst name="responseHeader"><int name="status">0</int><int name="QTime">1</int><lst name="params"><str name="q">*:*</str></lst></lst><result name="response" numFound="0" start="0"/> </response> * Connection #0 to host localhost left intact * Re-using existing connection!
