             Summary: Create Dispatch implementation that is configurable via service.xml file
                 Key: KNOX-1559
                 URL: https://issues.apache.org/jira/browse/KNOX-1559
             Project: Apache Knox
          Issue Type: Improvement
    Affects Versions: 1.3.0
            Reporter: Robert Levas
             Fix For: 1.3.0


Create a {{org.apache.knox.gateway.dispatch.Dispatch}} implementation that is configurable via metadata file (for example, {{service.xml}}).   Configurable parameters should be 
* headers to exclude when forwarding requests
* whether parameters should URL-encoded or not

Such an implementation should be able to make at least the following Dispatch implementations obsolete:
* org.apache.knox.gateway.dispatch.PassAllHeadersNoEncodingDispatch
* org.apache.knox.gateway.dispatch.PassAllHeadersDispatch

A possible declaration could be:
{code}
    <dispatch classname="org.apache.knox.gateway.dispatch.ConfigurableDispatch">
       <property>
           <name>excludeHeaders<name>
           <value>Authorization, Content-Length</value>
       </property>
       <property>
           <name>removeUrlEncoding<name>
           <value>false</value>
       </property>
    </dispatch>
{code}

Or maybe
{code}
    <dispatch classname="org.apache.knox.gateway.dispatch.ConfigurableDispatch" removeUrlEncoding="true" excludeHeaders="Authorization, Content-Length" />
{code}
