If you are using the Secure Proxy Server, you may have a need for your back end application to know the client IP address to do some specific actions.
It is not currently possible out of the box.
There are 3 different possible options:
- Have a load balancer in front of the SPS to set an X_FORWARDED_FOR header (containing the the client IP address) before it passed through the SPS server.
- Write a custom filter that would write a custom header like client_IP that would contain the original client header. This would need an extra development and would impact the apache reverse proxy module inside SPS. This is a custom solution that involve CA Services.
- Open an Enhancement Request through the Communities idea wall web site to have this functionality in as future release of the product.
