|

<p>Provides a mechanism for trying two extractors, a primary and a fallback. Useful for

“polymorphic payloads” where, for example, a form might be JSON or URL encoded.</p>
|

<p>It is important to note that this extractor, by necessity, buffers the entire request payload

as part of its implementation. Though, it does respect any <code>PayloadConfig</code> maximum size limits.</p>
