If you do not have a proxy server or do not wish to setup your proxy with X-Forwarded-* headers, you can configure frevvo's ''frevvo.forms.server.external.url'' context parameter. Once again, you set this parameter in config.properties (Weblogic) or frevvo.xml (Tomcat). This parameter contains the complete URL e.g. https://ext.my.com:8384. frevvo will always redirect to this server. Captcha requests will use the same protocol (HTTP or HTTPS) as the external URL.====

No proxy or external URL

...

If you do not have a proxy and do not set an external URL, frevvo will simply use the protocol, host and port of the inbound request i.e. it will assume that the server on which it received the request is the externally visible server.
