    Hi Jyoti,
    
    I need a lot more detail than “it didn’t work”. What didn’t work about it? Do
you have a log
    file? What site were you trying to crawl? What command did you use? Where is your nutch
    config? Were you running in distributed or local mode?
    
    Onto Selenium – have you tried it or simply reading the docs, you think it’s old?
What have
    you done? What have you tried?
    
    I need a LOT more detail before I (and I’m guessing anyone else on these lists) can
help.
    
    Cheers,
    Chris

    Hi Chris/Team,
    
    Whitelisting domain name din't work.
    And when i was trying to configure selenium. It need one headless browser to be integrated
with.
    Documentation for selenium-protocol plugin looks old. firefox-11 is now not supported
as headless browser with selenium.
    So please help me out in configuring selenium plugin configuration.
    
    I am yet not sure, after configuring above what result it will fetch me.
    
    With Regards,
    Jyoti Aditya

    Hi Chris,
    
    Whitelist din't work.
    And I was trying to configure selenium with nutch.
    But I am not sure that by doing so, what result will come.
    And also, it looks very clumsy to configure selenium with firefox.

    Hmm, I’m a little confused here. You were first trying to use white list robots.txt,
and now
    you are talking about Selenium.
    
    
    1.       Did the white list work
    
    2.       Are you now asking how to use Nutch and Selenium?
    
    Cheers,
    Chris

    Hi Chris,
    
    Thanks for the response.
    I added the changes as you mentioned above.
    
    But I am still not able to get all content from a webpage.
    Can you please tell me that do I need to add some selenium plugin to crawl
    dynamic content available on web page?
    
    I have a concern that this kind of wiki pages are not directly accessible.
    There is no way we can reach to these kind of useful pages.
    So please do needful regarding this.
    
    
    With Regards,
    Jyoti Aditya

        Sure, you can remove the check from the code and recompile.
    
        Under what circumstances would you need to ignore robots.txt ? Would
        something like allowing access by particular IP or user agents be an
        alternative ?
