Slideshows

Slideshows are using the reverse HTTP connection for asynchronous loading of pictures. Three connections are performed in parallel. The X-Apple-Purpose header is set to slideshow. A GET request to the /slideshows/1/assets/1 location is issued to fetch a new picture from the AirPlay client. A binary property list with the following parameters is expected as reply:

keytypedescription
datadataJPEG picture
info.idintegerasset ID
info.keyinteger1
