Hi Luke, hi Nima, > The/Robot Exclusion Standard/does not mention anything about the "*" > character in > the|Disallow:|statement. Indeed the RFC draft [1] does not. However, since Google [2] does wild card patterns are frequently used in robots.txt. With crawler-commons 0.4 [3] these rules are also followed by Nutch (to be in versions 1.9 resp. 2.3).
But the error message is about the noindex lines: noindex: *natuzzi* These lines are redundant (and also invalid, I suppose): if a page/URL is disallowed, it's not fetched at all, and will hardly slip into the index. I think you can ignore the warning. > One might also question the craw-delay setting of 120 seconds, but that's > another issue... Yeah, it will take very long to crawl the site. With Nutch the property "fetcher.max.crawl.delay" needs to be adjusted: <property> <name>fetcher.max.crawl.delay</name> <value>30</value> <description> If the Crawl-Delay in robots.txt is set to greater than this value (in seconds) then the fetcher will skip this page, generating an error report. If set to -1 the fetcher will never skip such pages and will wait the amount of time retrieved from robots.txt Crawl-Delay, however long that might be. </description> </property> Cheers, Sebastian [1] http://www.robotstxt.org/norobots-rfc.txt [2] https://developers.google.com/webmasters/control-crawl-index/docs/robots_txt [3] http://crawler-commons.googlecode.com/svn/tags/crawler-commons-0.4/CHANGES.txt On 05/31/2014 04:27 PM, Luke Mawbey wrote: > From wikipedia: > The/Robot Exclusion Standard/does not mention anything about the "*" > character in > the|Disallow:|statement.
