Hello Everyone,

I am using apache nutch to crawl HTTP websites. But when I try to crawl
HTTPS site its throwing the following error.

“failed with: org.apache.nutch.protocol.ProtocolNotFound: protocol not found
for url=https:


I searched the forums and there were some suggestions to enable the
“protocol-httpclient” plugin in nutch-site.xml.   Here is the plugin that I
use in my nutch-site .xml  file
<configuration>
<property>
  <name>plugin.includes</name>
 
<value>protocol-httpclient|urlfilter-regex|parse-(html|tika)|index-(basic|anchor)|scoring-opic|urlnormalizer-(pass|regex|basic)</value>
  <description>Regular expression naming plugin directory names to
  include.  Any plugin not matching this expression is excluded.
  In any case you need at least include the nutch-extensionpoints plugin. By
  default Nutch includes crawling just HTML and plain text via HTTP,
  and basic indexing and search plugins. In order to use HTTPS please enable 
  protocol-httpclient, but be aware of possible intermittent problems with
the 
  underlying commons-httpclient library.
  </description>
</property>

</configuration>

Do you guys have any other suggestions on how to crawl https websites ?

Your help is greatly appreciated,


Thanks a lot in advance,
-Kay
