Timur Irmatov created TS-1465:
---------------------------------
Summary: Handling of HTTP 0.9 responses
Key: TS-1465
URL: https://issues.apache.org/jira/browse/TS-1465
Project: Traffic Server
Issue Type: Improvement
Components: HTTP
Affects Versions: 3.2.0
Reporter: Timur Irmatov
I have a following scenario:
Apache Traffic Server is configured as forward proxy to access internet. (It
can be either explicit configuration or transparent - same problem). Then,
client (tested with linux music players MPD, Audacious, Rhythmbox) starts to
play internet radio, http://scfire-dtc-aa04.stream.aol.com/stream/1065 for
example. Origin server responds with HTTP 0.9, as fas as I understand. ATS
sends to client HTTP/1.1 response with chunked encoding. Unfortunately, none of
the aforementioned clients really understand HTTP/1.1 and chunked encoding in
particular. This leads to audible music defect every second or so. Granted,
these are bugs in those players, and I have reported it against one of them and
am willing to do so for others.
But, Squid proxy acting as transparent proxy forwards original servers' HTTP
0.9 repsonse back to client not modified at all (without upgrading it to
HTTP/1.1 despite client request claims HTTP/1.1). So no problem. Is there a
possibility to may be add configuration variable (something like
proxy.http.return_http09_as_is) to mimic Squid's behaviour and return HTTP 0.9
response body as is, without any modifications or reponse version upgrade?
This is request from curl and Squid's response:
Request:
