What exactly is blockAddr(url) doing

[Chetan Sahasrabudhe]

Hi,

      I am still trying to get my nutch fetcher run through proxy.
I have made a small change in, 

Http.java under configureClient() method

      //client.getState().setCredentials(null, null, ntCreds);
      client.getState().setProxyCredentials(null, null, ntCreds);

I have explicitly called setProxyCredentials and it is working fine. Not I am 
no more getting 407's.

Once I get robots.txt file from server and run it through, isAllowed.

The code fails at blockAddr(url) call. Me still trying to figure out what this 
call is doing.

Any help is welcome.

Regards
Chetan
