Proven Performance. No Middleware. Pure CICS.

CGI Interface

Superior CGI programming interface shields CICS programmers from HTTP header complexities — making web development as natural as existing CICS development.

Server-Side Includes

SSI cleanly separates business logic (CICS) from presentation (HTML), increasing productivity without writing programs for static content. Single-pass HTML and XML template processing.

Sendmail API

Built-in Sendmail API lets CICS programs send email directly — no additional middleware required. Static pages and graphics are handled by the complete web server.

Performance

Inline compression improves response time. HTML and XML template caching delivers high throughput for CICS web applications under load.

SSL & Security

CICS security exit and SSL encryption options secure client connections. Full support for CICS, VSE, OS/390, and z/OS versions.

Reduces time and expense of developing CICS powered Web application and XML Web Services by eliminating the need for specialized client development.

Increases productivity without having to write a program to handle every request (e.g., static web pages, graphics, applets, etc.)

Increases ease-of-use with Server-Side Includes (SSI) for easy separation of business logic (CICS code) and presentation (HTML).

Improves response time through in-line compression.

Boosts productivity by shielding CICS programmers from complexities of HTTP headers and input parsing.

Speeds up processing with a superior “single pass” HTML and XML Template processing with support for passing data in CICS Temporary Storage.

What do you do when screen scraping just isn’t enough for your application? Taking the time to create a 3270 screen just to screen scrape is a waste of time. Programmer friendly CICS CGI Web development environments will allow you to be free of 3270 and its inherent constraints.

IpServer is a proven low cost CICS based Web Server that runs in virtually all levels of CICS under MVS, OS/390 and VSE. IpServer’s superior CGI programming interface and unique performance features enable CICS programmers to quickly leverage existing systems and skills to transform strategic CICS business applications into high-performance state-of-the-art Web Applications.
