Tejas Patil commented on NUTCH-1513:
------------------------------------
For this has to be supported I have 2 approaches:
# Implement robots handling for Ftp in a similar way as its been done for Http
protocol. Parsing performed by Nutch.
# Same as #1 but use Crawler-Commons to get the parsing done. There is already
[NUTCH-1031|https://issues.apache.org/jira/browse/NUTCH-1031] filed for its
integration with Nutch. The [last
release|http://code.google.com/p/crawler-commons/downloads/list] of
Crawler-Commons was in July 2011. Looks like it aint under active development.
Please let me know your comments about these approaches.
