Popup window from remote CGI?

[islandwifibill]

Hi All,

I wrote a cgi script that pops up a window letting the user know their account status.  The script resides on my web server, which is NOT the pfsense machine.  However, when I upload the captive portal page and test the popup, it just delivers a blank page (the popup is blank, that is).

This popup is generated by a javascript (on my captive portal page) which invokes a php cgi script (residing on my webserver).  In testing, it works from my webserver.

The Question:  is the captive portal set up to refuse remote cgi-bin calls on the captive portal login?

Any input would be appreciated, but definitive answers are of course preferred, lol  ;)
