Hi
We have a clientless VPN and app set up to use https on tcp 8443 but the page is not displaying at all. Connectivity has been proven end to end so all the rules are in place.
The app points to a webserver that hosts a portal and uses Javascript.
Some debugging was carried out on the client browser side and a comparison of going through the clientless VPN and not going through the VPN showed the Palo inserting various code. I know the Palo does URL re-writes but can anyone explain what the "pan_eval((function()" and "?gp-7" is? I guess it's something to do with Java but unfortunately I have no experience of it.
Many thanks.
Paul.
These are some of the extracts from the debug whilst going through the VPN and the inserted elements:
<script src="https://xxx.xxx.xxx.254/global-protect/vpn-js/pan_js_all_181s.js"></script><base href="/http-8443/xxx.xxx.xxx.31/aiv/">
<script type="text/javascript" src="assets/js/css-vars-ponyfill.min.js?gp-7"></script>
<script type="text/javascript">
pan_eval((function()
This whole content has been added by the Palo:
).toString().slice(12, -2),__pan_site_rules,1);</script>
