Hi, I am benchmarking HttpCore 5.1-Beta. When running under load HTTP clear text tests I am seeing frequent protocol errors reported. Using Wireshark to trace the interface.

The load driver pushing GET requests for files. A mixture of text or binary. I checked JIRA and found no reported issues. I know this as BETA release I'm using. Is this api expected to work without issue ?
