Query parameters are not passed in HLS playlist file in Mozilla but working fine in Chrome

[KS_Dwivedi]

I have a VOD server(Wowza) and now want to integrate it with Akamai CDN. I am using a secure token as query parameter. The URL I am calling with player is:

https://**********akamai.net/vod_app_name/smil:112233445577.smil/playlist.m3u8?hdnea=exp=1555432114~acl=/*~hmac=11c4f9a352200348d58fb77cf64bf437fa60ea3ab4b2bae60bdb157b11beb1cb

And the response I get in Chrome, Safari & Opera is:

<code>#EXTM3U
#EXT-X-VERSION:3
#EXT-X-STREAM-INF:BANDWIDTH=264000,RESOLUTION=256x144
chunklist_b264000_sleng.m3u8?hdntl=exp=1555500589~acl=/*~data=hdntl~hmac=58640a72653d2d384e70326656b33601bd2c159d5ecfe25cdb474f2b2012aa04

But in Mozilla firefox the response is not having the query-parameters, it looks like:

<code>#EXTM3U
#EXT-X-VERSION:3
#EXT-X-STREAM-INF:BANDWIDTH=264000,RESOLUTION=256x144
chunklist_b264000_sleng.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=375000,RESOLUTION=426x240
chunklist_b375000_sleng.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=475000,RESOLUTION=640x360
chunklist_b475000_sleng.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=575000,RESOLUTION=854x480
chunklist_b575000_sleng.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=875000,RESOLUTION=1280x720
chunklist_b875000_sleng.m3u8

I tried with other HLS URLs (with no Akamai CDN), and in Mozilla everything is working fine.

Akamai guys are saying that there is no problem at there end, I tried with different systems & different ISPs but the same result.

I also tried changing “referer header” (user agent) in browser. Even in Chrome when referer is set to “Mozilla/5.0 (Windows NT 10.0; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0” the playlist is returned without query parameters. And when in Firefox, I change the user agent the query parameters are present. So it has something to do with user agent.

The same issue is there with DASH, it’s not only HLS issue.

Thanks for the question @KS Dwivedi. Wowza only supports live streaming to a CDN at this time. We do not provide support for VOD workflows to a CDN like Akamai. Sorry for any inconvenience this causes you.
