Hi, I want to use wowza 3.6.2 as HTTP origin for all http segmented protocols, specially for live streaming.

I would use a 3rd party CDN http cache infrastructure for it.

However I have some doubts I need to solve to obtain the expected behaviour.

The doubs are the following:

- I want to bypass proxy-caches when downloading the playlist files, because of their dynamic content, and because I want to build a module able to get the forwared ip as my real connected client from the header of the reverse-proxy requests to wowza.

For ensuring this behaviour, what is best suited value for Cache-control at wowza responses ?

max-age=1 ? max-age=0 ? no-cache ? private ?

- I want media files to be served from the proxy-caches when available, because of their static content, and settle a TTL of no more than 100 seconds (no need to store it longer for a livestream).

Is max-age=100 a good value for Cache-control ?

Thanks in advance for your valuable help.

Best regards,

BH

BH,

Here is some info:

For what you want to accomplish the playlist cache control header should be no-cache. That should instruct the proxy to always get the content from the source. Of course this assumes the proxy server is behaving correctly.

For the media chunks a time to live of 100 should be fine. Yes just set max-age=100. That should work fine.
