> Html redirections using meta tags are supported in nutch. They work well when using parse-html
to parse files. However, when using parse-tika, they are not detected.
> This is because of https://issues.apache.org/jira/browse/TIKA-2652
> Tika emits redirection meta tags as :
> {code:xml}
> <meta name="refresh" content="0; url=http://example.com"/>
> {code}
> whereas org.apache.nutch.parse.tika.HTMLMetaProcessor expects meta tags having the following
format :
> {code:xml}
> <meta http-equiv="refresh" content="0; url=http://example.com">
> {code}
> The bug can be reproduced with the following nutch-site.xml:
> {code:xml}
> <?xml version="1.0"?>
> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
> <!-- Put site-specific property overrides in this file. -->
> <configuration>
>     <property>
>         <name>plugin.includes</name>
>         <value>protocol-http|parse-tika</value>
>     </property>
>     <property>
>         <name>http.agent.name</name>
>         <value>blah</value>
>     </property>
> </configuration>
> {code}
> fetching this url: http://www.google.com/policies/technologies/ads/
> The resulting status is {code}success(1,0){code} whereas using parse-html, the resulting
status is {code:html}success(1,100), args[0]=https://policies.google.com/technologies/ads,
args[1]=0{code}
