    configuration edge- and origin-apps builds closely to sample, exept app names.
    developer-lisence, origin on win7, edge on debian 6, network issues, such as firewalls, etc, are excluded

    Yes, it should work. Have you seen this method of caching chunks on the edge, not sure but it might help you in this case:

    This may be related with my problem ?
    Yes, i seen this technology, and i planned to use it in future - I already sent request to your support for taking this addon.
    Please, ask me, what kind of environment (os, license, version of wowza ) was used for writing this article ?

    I tested dvr origin/edge following that guide. I used RTMP live encoder as source. I did not use the MediaCache addon. I was able to continue playback from the edge using the Wowza /examples/LiveDVRStreaming/FlashHTTPPlayer after stopping the stream, and after disconnecting the encoder.

    I tested configurations with mediacache - and i got the same result. All works fine, before restart origin, or, my be, same timeout after closing DVR.
