Permit differing IP addresses from same browser

VARIPADDR is a parameter on JANUS DEFINE, which defines and sets characteristics of a Janus port.

VARIPADDR indicates that a single browser might access Janus Web Server using different IP addresses (probably because it's accessing Janus Web Server through a "proxy farm"), so Janus Web Server should not use the IP address to decide whether a set of requests all came from the same browser or not.

A proxy farm is a collection of proxy servers that act more or less as one proxy server from a browser's perspective. In a proxy farm, a browser might be moved around between different proxies, most likely for load-balancing purposes.

Setting VARIPADDR reduces Janus Web Server's ability to distinguish requests from multiple browsers, potentially causing problems with legacy sessions and persistent sessions (especially on public URLs), or slightly reducing the efficacy of session cookies. Nevertheless, VARIPADDR is more or less unavoidable if users are accessing Janus Web Server through proxy farms.

Valid only for WEBSERV ports.
