This middleware enables content encoding of http responses, usually for purposes of compression.

Currently supported encodings:
<ul><li>
gzip
</li><li>
identity (no transformation)
</li></ul>

This middleware automatically detects when encoding is supported and allowed. For example no encoding is made when a cache directive of &#39;no-transform&#39; is present, when the response status code is one that doesn&#39;t allow an entity body, or when the body is empty.

Note that despite the name, <a href="Deflater.html"><code>Deflater</code></a> does not support the <code>deflate</code> encoding.

 Creates <a href="Deflater.html"><code>Rack::Deflater</code></a> middleware. Options:
<dl class="rdoc-list note-list"><dt>:if 
<dd>
a lambda enabling / disabling deflation based on returned boolean value (e.g <code>use Rack::Deflater, :if =&gt; lambda { |*, body| sum=0; body.each { |i| sum += i.length }; sum &gt; 512 }</code>). However, be aware that calling `body.each` inside the block will break cases where `body.each` is not idempotent, such as when it is an <code>IO</code> instance.
</dd><dt>:include 
<dd>
a list of content types that should be compressed. By default, all content types are compressed.
</dd><dt>:sync 
<dd>
determines if the stream is going to be flushed after every chunk. Flushing after every chunk reduces latency for time-sensitive streaming applications, but hurts compression and throughput. Defaults to <code>true</code>.
