> We noticed that there's an "out of order sequence response" error immediately 
> after an http error or premature context closure. We are seeing a lot of 
> these in production.
> It seems like THttpClient does not reset it's internal buffer when http 
> client returns an error, leaving the whole or partially read message in the 
> buffer. On next call THttpClient sends the remains of previous message 
> followed by current message, causing the server to execute it  and return the 
> previous seqId hence the  "out of order sequence response" errors.
> Here's a small test of THttpClient that demonstrates this issue: 
> [https://github.com/wheely/thrift/blob/c130f2452428540a4eefc4c422c8abc329ec837d/lib/go/thrift/http_client_test.go#L101-L147]
>  .
> First flush fails due to closed context, second flush succeeds but writes 
> both messages to the server. In current thrift version this test fails with:
> {code:java}
> http_client_test.go:144: Received unexpected data: write 1write 2{code}
>  
> Please let me know if you need a better example.
