An HTTP(S) proxy server for online license verification can now be configured in License settings.

Sites that require the use of a proxy server for outbound HTTP(S) traffic can now be configured appropriately in Checkmk UI under Setup -> Maintenance -> Licensing.

Previously such sites had to resort to offline verification, configuring proxy servers via environment variables, or making exceptions to network policies.

No configuration changes are necessary to existing sites, even if they had been using environment variables http_proxy/https_proxy (and similar). These environment variables will still be honoured, unless explicitly overridden in Checkmk settings.
