+<body>
+ <h2>General</h2>
+ <p>This lookup service has the following required keys:</p>
+ <ul>
+ <li>mime.type</li>
+ <li>request.method; valid values:
+ <ul>
+ <li>delete</li>
+ <li>get</li>
+ <li>post</li>
+ <li>put</li>
+ </ul>
+ </li>
+ </ul>
+ <p>In addition to the required keys, a key "body" can be added which
contains a string representing JSON, XML, etc. to be sent with any
+ of those methods except for "get."</p>
+ <p>The record reader is used to consume the response of the REST
service call and turn it into one or more records. The record path property
+ is provided to allow for a lookup path to either a nested record or a
single point deep in the REST response. Note: a valid schema must be
+ built that encapsulates the REST response accurately in order for this
service to work.</p>
+ <h2>Headers</h2>
+ <p>Headers are supported using dynamic properties. Just add a dynamic
property and the name will be the header name and the value will be the value
for the header. Expression language
+ powered by input from the variable registry is supported.</p>
+ <h2>Dynamic URLs</h2>
+ <p>The URL property supports expression language in a non-standard
way: through the lookup key/value pairs configured on the processor. The
configuration specified by the user will be passed
