/**
 * SECTION:element-souphttpsrc
 *
 * This plugin reads data from a remote location specified by a URI.
 * Supported protocols are 'http', 'https'.
 *
 * An HTTP proxy must be specified by its URL.
 * If the "http_proxy" environment variable is set, its value is used.
 * If built with libsoup's GNOME integration features, the GNOME proxy
 * configuration will be used, or failing that, proxy autodetection.
 * The #GstSoupHTTPSrc:proxy property can be used to override the default.
 *
 * In case the #GstSoupHTTPSrc:iradio-mode property is set and the location is
 * an HTTP resource, souphttpsrc will send special Icecast HTTP headers to the
 * server to request additional Icecast meta-information.
 * If the server is not an Icecast server, it will behave as if the
 * #GstSoupHTTPSrc:iradio-mode property were not set. If it is, souphttpsrc will
 * output data with a media type of application/x-icy, in which case you will
 * need to use the #ICYDemux element as follow-up element to extract the Icecast
 * metadata and to determine the underlying media type.
 *

 * ]| The above pipeline reads a web page from a server using the HTTPS protocol
 * and writes it to a local file.
 * |[
 * gst-launch-1.0 -v souphttpsrc user-agent="FooPlayer 0.99 beta"
 *     automatic-redirect=false proxy=http://proxy.intranet.local:8080

 *     ! audioresample ! alsasink
 * ]| The above pipeline will read and decode and play an mp3 file from a
 * web server using the HTTP protocol. If the server sends redirects,
 * the request fails instead of following the redirect. The specified
 * HTTP proxy server is used. The User-Agent HTTP request header
 * is set to a custom string instead of "GStreamer souphttpsrc."
 * |[
 * gst-launch-1.0 -v souphttpsrc location=http://10.11.12.13/mjpeg
 *     do-timestamp=true ! multipartdemux
 *     ! image/jpeg,width=640,height=480 ! matroskamux
 *     ! filesink location=mjpeg.mkv
 * ]| The above pipeline reads a motion JPEG stream from an IP camera
 * using the HTTP protocol, encoded as mime/multipart image/jpeg
 * parts, and writes a Matroska motion JPEG file. The width and
 * height properties are set in the caps to provide the Matroska
 * multiplexer with the information to set this in the header.
 * Timestamps are set on the buffers as they arrive from the camera.
 * These are used by the mime/multipart demultiplexer to emit timestamps
 * on the JPEG-encoded video frame buffers. This allows the Matroska
 * multiplexer to timestamp the frames in the resulting file.
