Introduction
In addition to offloading interrupt-intensive communications tasks from clients, a Pro-
togate Freeway communications server can offload additional applications processing
with its unique server-resident application (SRA) functionality. SRAs operating on a
Freeway server can execute such functions as data screening/stripping, data compres-
sion, byte swapping, character translation, protocol conversion, and encryption.
This document describes how to implement server-resident applications on a Freeway
server. It describes the environment in which your SRA application will execute and
shows examples of the Freeway server elements your application can use to access
Freeway resources.
Some of the information required to develop an SRA is in other documents such as:
• Protogate’s Freeway Client-Server Interface Control Document
• Protogate’s Freeway Data Link Interface Reference Guide
• Protogate’s Freeway Transport Subsystem Interface Reference Guide
• Protogate’s Freeway User’s Guide
This manual assumes that you are familiar with the concepts described in these other
documents.
1.1 Freeway Server-Resident Applications (SRAs)
An SRA is fundamentally an application that resides and operates in the FreeBSD envi-
ronment on the Freeway server. You may build applications directly on your Freeway
