Failover support

Origin Server does not modify the m3u8 posted to it. Encoder or packager publishing the m3u8 files need to ensure that m3u8 is HLS standard compliant. The encoder or packager should update the m3u8 file in a consistent manner.

Following are the constraints for consistent generation of m3u8:

• After a segment is assigned a sequence number, it cannot change.
• Sequence number should increase. Encoder or packager cannot introduce jumps in sequence number without removing all the previous entries from the m3u8 file.
