Hi,
http.agent.version defaults in nutch-default.xml to Nutch-1.14-SNAPSHOT (depending on the version of course). If I want to override it to not send a version as part of the user-agent, there is nothing I can do in nutch-site.xml, since putting an empty string there causes the default to be taken, and putting any value there causes a slash to be appended to the http.agent.name. As far as I can see, the only way to override it is to remove the value in nutch-default.xml, which is probably not the "correct" way, considering it contains a comment saying "Do not modify this file directly". This was asked previously in https://www.mail-archive.com/[email protected]/msg15341.html, but without a helpful answer. I would be willing to push a fix where setting the string to "null" would cause it to be ignored, if the maintainers are on board. Yossi.
