libsoup2.2-doc 2.2.95.1-0ubuntu1 (i386 binary) in ubuntu edgy

 It was originally part of a SOAP (Simple Object Access Protocol)
 implementation called Soup, but the SOAP and non-SOAP parts have now been
 split into separate packages.
 .
 libsoup uses the Glib main loop and is designed to work well with GTK
 applications. This enables GNOME applications to access HTTP servers
 on the network in a completely asynchronous fashion, very similar to
 the Gtk+ programming model (a synchronous operation mode is also
 supported for those who want it).
