Subject [jira] [Commented] (NUTCH-1995) Add support for wildcard to http.robot.rules.whitelist
Date Tue, 26 May 2015 21:16:18 GMT

    [ https://issues.apache.org/jira/browse/NUTCH-1995?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14559883#comment-14559883
] 

Sebastian Nagel commented on NUTCH-1995:
----------------------------------------

+1, yes
* there is already an output / log message about whitelisted URLs/hosts either in RobotsRulesParser's
main() or in getRobotRulesSet(): do we need an additional log message on level INFO (cf. discussion
in NUTCH-1927)? Logging is now a somewhat redundant:
{noformat}
2015-05-26 23:13:58,402 INFO  protocol.RobotRulesParser - localhost is whitelistened: true
2015-05-26 23:13:58,405 INFO  api.HttpRobotRulesParser - Whitelisted host found for: http://localhost
2015-05-26 23:13:58,405 INFO  api.HttpRobotRulesParser - Ignoring robots.txt for all URLs
from whitelisted host: localhost
{noformat}

> The {{http.robot.rules.whitelist}} ([NUTCH-1927|https://issues.apache.org/jira/browse/NUTCH-1927])
configuration parameter allows to specify a comma separated list of hostnames or IP addresses
to ignore robot rules parsing for.
> Adding support for wildcard in {{http.robot.rules.whitelist}} could be very useful and
simplify the configuration, for example, if we need to give many hostnames/addresses. Here
is an example:
> {noformat}
> <name>http.robot.rules.whitelist</name>
>   <value>*.sample.com</value>
>   <description>Comma separated list of hostnames or IP addresses to ignore 
>   robot rules parsing for. Use with care and only if you are explicitly
>   allowed by the site owner to ignore the site's robots.txt!
>   </description>
> </property>
> {noformat}
