Hi!

I see different behaviors when requesting a File that doesnt exist

on Wowza 3.5 I get an empty manifest

```auto
<?xml version="1.0" encoding="utf-8"?>
<SmoothStreamingMedia MajorVersion="2" MinorVersion="1" Timescale="10000000" Duration="0">
</SmoothStreamingMedia>

```

e.g. here

[http://194.232.200.47/cms-austria/mp4:teererst.mp4/Manifest](http://194.232.200.47/cms-austria/mp4:teererst.mp4/Manifest)

on Wowza 4.0.3 I get Error 404

System.Net.WebException: The remote server returned an error: (404) Not Found.

e.g. here

[http://185.85.28.1:1935/cms-austria/mp4:teeest.mp4/Manifest](http://185.85.28.1:1935/cms-austria/mp4:teeest.mp4/Manifest)

Is there any posibility to get also an empty manifest file on newer Wowza Versions??

Regards

Robert

Hi Robert,

You can opt to create a SMIL file that points to your VOD asset, and use the SMIL file in your playback URL instead. If the VOD file referred to in the SMIL cannot be found, then the HTTP request should return an empty manifest.
