---------------------------------------
Here's an example garbage SYN_REPLY:
{code}
[ 0.010] NPN select next protocol: the remote server offers:
* spdy/3.1
* spdy/3
* http/1.1
* http/1.0
NPN selected the protocol: spdy/3
[ 0.017] Handshake complete
[ 0.017] send SYN_STREAM frame <version=3, flags=0, length=261>
(stream_id=1, assoc_stream_id=0, pri=3)
:host: dev1.stg.uff.corp.gq1.yahoo.com
:method: POST
:path: /
:scheme: https
:version: HTTP/1.1
accept: */*
accept-encoding: gzip, deflate
content-length: 9248
user-agent: spdylay/1.2.3
[ 0.017] send DATA frame (stream_id=1, flags=0, length=4096)
[ 0.017] send DATA frame (stream_id=1, flags=0, length=4096)
[ 0.017] send DATA frame (stream_id=1, flags=0, length=1056)

> Project: Traffic Server
> Issue Type: Bug
> Components: SPDY

> Seeing some HTTP/0.9 version garbage responses with status=0 from SPDY
> sometimes. In some error cases, when http layer cleans up itself and sends a
> FETCH ERROR to the SPDY layer and SPDY layer seems to build a SYN_REPLY with
> garbage HTTP headers. Adding a simple protection to prevent this.
