#970: partial content code 206 - visible as '206' in varnishncsa and as '200'
from VCL code
-------------------------------------------------+--------------------------
Reporter: jhalfmoon | Type: defect
Status: new | Priority: normal
Milestone: | Component: varnishd
Version: 3.0.0 | Severity: normal
Keywords: 206 partial content varnishncsa vcl |
-------------------------------------------------+--------------------------
Hi there,
It seems that when varnishd returns partial content to a browser,
Varnishnsca properly logs the transfer with a code 206 'partial content',
but logging the exact same transfer from VCL code, it returns code '200',
which is incorrect. I have tried using VRT_r_obj_status, VRT_r_rest_status
and VRT_r_beresp status to no avail. This is the case with both Varnish
2.1.5 and 3.0.0.
Is this done on purpose by the code or can it be registered as a bug? This
is how I test it (examples using Varnish 3.0.0):
#=== The command to do the RANGE request (note the returncode 206 'partial
content) ===
testproxy02 ~ # http_proxy=http://127.0.0.1:80 curl -v -r 500-1000
http://vi.nl
.
.
Proxy-Connection: Keep-Alive
< HTTP/1.1 206 Partial Content < Server: Apache
.
...<output truncated>...
#=== This is the output of varnishncsa (note the code '206')===
testproxy02 ~ # varnishncsa 127.0.0.1 - - [28/Jul/2011:17:17:23 +0200]
"GET http://bla.nlhttp://bla.nl HTTP/1.1" 206 501 "-" "curl/7.15.5 (x86_64
-redhat-linux-gnu) libcurl/7.15.5 OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5"
#=== This is the output I get in syslog (note the code '200') ===
testproxy02 ~ # tail -f /var/log/varnish/current
code:200
127.0.0.1 - - "Thu, 28 Jul 2011 15:16:56 GMT" "GET http://bla.nl" 200

OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5" X:616508938 B:bla_nl V:bla.nl h:1
#=== This is the bit of inline C code used to do the loggin from VCL ===
int mycode = VRT_r_resp_status(sp);
if (mycode == NULL) { mycode = 0; }
syslog(LOG_DEBUG, "code:%u ", mycode );
.
...<output truncated>...
#=== EOF ===
