Sandeep More commented on KNOX-1277:
------------------------------------

Thanks for linking the issue [~risdenk] ! This one is a special case (looks 
like every case is :)), the hdfs UI uses the Meta tag
{code:java}
<meta http-equiv="REFRESH" content="0;url=dfshealth.html"/>{code}
one of the things I am playing around is using the prefix rule, given how picky 
Knox is there are certain symbols that have special meaning, like =, so they 
need to be encoded, since we use XML parser to parse rewrite.xml file, this XML 
safe encoding will be lost (the parser will replace it, and rightly so), this 
was the rule that I found worked for me (use &equals; to encode = )
{code:java}
  <rule dir="OUT" name="HDFSUI/hdfs/inbound/namenode/root/filter/refresh-tag">
     <rewrite template="{$prefix[0;url&amp;#61;,url]}/hdfs/dfshealth.html"/>
   </rule>{code}
