-<p class="level0">Sets the contents of the Accept-Encoding: header sent in a HTTP request, and enables decoding of a response when a Content-Encoding: header is received. Three encodings are supported: <span Class="emphasis">identity</span>, which does nothing, <span Class="emphasis">deflate</span> which requests the server to compress its response using the zlib algorithm, and <span Class="emphasis">gzip</span> which requests the gzip algorithm.

Three encodings are supported: <span Class="emphasis">identity</span>, meaning non-compressed, <span Class="emphasis">deflate</span> which requests the server to compress its response using the zlib algorithm, and <span Class="emphasis">gzip</span> which requests the gzip algorithm.
<p class="level0">If a zero-length string is set like "", then an Accept-Encoding: header containing all built-in supported encodings is sent.
+<p class="level0">Set this option to NULL to explicitly disable it, which makes libcurl not send an Accept-Encoding: header and not decompress contents automatically.
<p class="level0">You can also opt to just include the Accept-Encoding: header in your request with <a Class="emphasis" href="./CURLOPT_HTTPHEADER.html">CURLOPT_HTTPHEADER</a> but then there will be no automatic decompressing when receiving data.
