In SAS^® 9.3, a SAS stored process can access a client application's IP address by referencing the _RMTADDR parameter that is passed to the SAS^® Stored Process Server. However, in SAS 9.4 and later, this parameter does not contain the IP address of the client application.

You can configure the SAS Stored Process Web Application to pass the value of the client application's IP address by following these steps:

1. Modify the Stored Process Web Application's Params.config file, which resides on the Application Web Server machine in a location similar to this:
   .../Lev1/Web/WebAppServer/SASServer1_1/sas_webapps/sas.storedprocess.war/Params.config
2. In the Params.config file, find the following line:
   
   _rmtaddr=$servlet.remote.addr
   Change the above line to this:
   _rmtaddr=$servlet.header.x-forwarded-for
3. Restart your Application Web Server to activate the change.
   
   

A stored process can access the _RMTADDR parameter value by referencing the &_RMTADDR macro variable.

When you submit a stored process request, specify /do (and not /do1) on the URL. Here is an example:

Note: If you install a later version of the Stored Process Web Application, you will need to modify the Params.config file again.
