Alternatively, [i](https://help.cloudtrax.com/hc/en-us/articles/204803954-Internally-Hosted-Splash-Page-with-RADIUS-Authentication)nternal splash page are simpler, but provide less flexibility. External splash pages are stored and executed on a web server that user define, and must respond appropriately to certain messages from the Access Point in order to present appropriate user-interface to the user at various stages of the authentication process. When combined with RADIUS Authentication, EnGeniusCloud will consult an external RADIUS server that you specify in order to determine whether to authenticate the user. The user interface presented to the user will be determined by the external splash page. Most EnGenius customers who need a captive portal authentication system on their wireless networks use the customizable splash pages that are hosted by EnGeniusCloud. However, some network administrators may prefer to host a captive portal page on their own servers. This Section shows you how to configure EnGeniusCloud to adopt external splash page with an external RADIUS server to handle authentication. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://doc.engenius.ai/home-cloud-white-papers/captive-portal/external-splash-page.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
