Using ks in the URL

Hi,

Is it correct to use a KS user string in the URL to retrieve a video under KS access control. For example:

https://cdnapisec.kaltura.com/p/9999999/sp/9999999/playManifest/entryId/1_xxxxxxx/ks/djJ8MjI4ODY5MXxCWfJDSkrokaM5CweYhCHG1LTm3cS3c6QVD1QfFPFGHIaI-pJkP9wASIVIi94BEMChcvMpaJolEs-sLmkbSON/format/url/flavorParamId/301971/video.mp4

The KS, is the same KS that I m able to get with the SessionStart API function?

thanks

Lluís
