Sebastian Nagel commented on NUTCH-1718:
----------------------------------------

Hi [~tejasp], +1 to "redefine" {{http.robots.agents}} as "additional agent names": makes it simpler for polite users which definitely should use the same user agent name in HTTP header and robots.txt.

> 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>
