--------------------------------------
Summary: protocol-okhttp: properly record HTTP version in request
message header
Key: NUTCH-2760
URL: https://issues.apache.org/jira/browse/NUTCH-2760
Project: Nutch
Issue Type: Bug
Components: plugin, protocol
Affects Versions: 1.16
Reporter: Sebastian Nagel
Fix For: 1.17
The HTTP version in the request message tracked by the plugin protocol-okhttp
({{store.http.request=true}}) is not the version sent in the request but that
received from the response.
Note that the HTTP version sent in the request may differ from that sent back
in the response. One example (tracked using wget):
{noformat}
> wget -d https://www.kp.ru/daily/27061/4129507/
...
---request begin---
GET /daily/27061/4129507/ HTTP/1.1
User-Agent: Wget/1.20.3 (linux-gnu)
Accept: */*
Accept-Encoding: identity
Host: www.kp.ru
Connection: Keep-Alive
---request end---
HTTP request sent, awaiting response...
---response begin---
HTTP/1.0 200 OK
...
{noformat}
protocol-http uses the response version ("HTTP/1.0") also for the request:
{noformat}
> bin/nutch parsechecker -Dstore.http.headers=true -Dstore.http.request=true \
-Dplugin.includes='protocol-okhttp|parse-html'
https://www.kp.ru/daily/27061/4129507/
...
_request_=GET /daily/27061/4129507/ HTTP/1.0
...
_response.headers_=HTTP/1.0 200 OK
...
{noformat}
The protocol-http tracks the versions correctly:
{noformat}
> bin/nutch parsechecker -Dstore.http.headers=true -Dstore.http.request=true \
-Dplugin.includes='protocol-http|parse-html'
https://www.kp.ru/daily/27061/4129507/
...
_request_=GET /daily/27061/4129507/ HTTP/1.1
...
_response.headers_=HTTP/1.0 200 OK
...
{noformat}
