Sebastian Nagel updated NUTCH-1718:
-----------------------------------
Attachment: NUTCH-1718-trunk.v2.patch
Updated patch:
* for backward compatibility: take care that agent name itself is not given
twice
* removed obsolete check whether http.agent.name is included in
http.robots.agents from Fetcher
Backward compatibility with "old" nutch-site.xml has been tested. I'll continue
testing. But would opt for applying this: the behavior of Nutch regarding
robots.txt has changed significantly with NUTCH-1759, and we can accept this
minor change.
> update description of property http.robots.agent

> The description of property http.robots.agent in nutch-default.xml recommends
> to add a '*' to the list of agent names. This will cause the same problem as
> described in NUTCH-1715. The description should be updated. Also regarding
> "order of precedence" which is dictated since NUTCH-1031 only by ordering of
> user agents in robots.txt.
> {code:xml}
> <property>
> <name>http.robots.agents</name>
> <value>*</value>
> <description>The agent strings we'll look for in robots.txt files,
> comma-separated, in decreasing order of precedence. You should
> put the value of http.agent.name as the first agent name, and keep the
> default * at the end of the list. E.g.: BlurflDev,Blurfl,*
> </description>
