Which webservers are supported?

Apache, Nginx, Lighttpd and IIS are supported.

Please see the Supported Webservers for details.

HTTP request methods

Unified Streaming supports the following request methods:

  • GET
  • POST

Other requests (e.g. HEAD, DELETE, PUT etc) will return a 405 HTTP_METHOD_NOT_ALLOWED.

In the case of Apache, OPTIONS is passed on to other handlers.

CORS headers

USP currently only supports GET and POST, OPTIONS are passed on in the case of Apache - so the following needs to be set in the (Apache virtual host config):

# Necessary for Media Source Extensions (MSE)
Header always set Access-Control-Allow-Headers "origin, range"
Header always set Access-Control-Allow-Methods "GET, HEAD, OPTIONS"
Header always set Access-Control-Allow-Origin "*"
Header always set Access-Control-Expose-Headers "Server,range"

Live Ingest

Please see the Which ingest formats are available? section on what is supported.

The protocol uses HTTP POST and requires 'HTTP Chuncked Transfer Encoding', which is not avalable in all webservers.


For Live ingest you have to use Apache (Linux or Windows).
