CodeIgniter setup behind IIS reverse proxy

Hi,

I'm trying to deploy a website built with CodeIgniter framework behind IIS reverse proxy server.

The website is setup on a server inside process control network, already tested and works fine. However after I setup the reverse proxy to access this website from outside of the network, the end-user in the business network who access it through the reverse proxy cannot display the website properly on their browser (ie. the CSS and the javascript is not working).

We need the reverse proxy because the actual web server is behind a firewall but needs to be accessed by users in the corporate network. The reverse proxy is using IIS URL Rewrite module.

Is this scenario possible or is there a known issue with the deployment of CodeIgniter-based website behind IIS reverse proxy (because both the CodeIgniter _and_ the IIS reverse proxy are using IIS URL Rewrite module). Thanks.

Regards,
Jati
