VARIPADDR (JANUS DEFINE parameter)

<section begin="desc" />Permit differing ipaddresses from same browser<section end="desc" />

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

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 that Janus Web Server should not use 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 and in which 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, 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".

The VARIPADDR parameter is available in Sirius Mods Version 6.0 and later.

Valid only for WEBSERV ports.
