SRF files are used by Xcentrisity Business Information Server to serve web pages and implement (not consume) SOAP services.  XBIS runs on an HTTP server like IIS or Apache.

SRF files are server-side only and not used in clients (unless the HTTP server is acting as a client).

SRF files are fully documented in the Xcentrisity Business Information Server User's Guide for Extend here:
