ERROR_INFO

Specifies the error code to determine the error page. For example:

401

HTTP_COOKIE

Contains the cookie that is sent with this request to communicate state information. For example:

CustomerNumber=HJ68944

You can find details about cookies at URL:

http://www.netscape.com/newsref/std/cookie_spec.html.

HTTP_REASON

Sets the reason string in the HTTP response header.

HTTP_RESPONCE

Sets the response code in the HTTP response header.

INIT_STRING

The string specified on the ServerInit directive.

LAST_MODIFIED

For example:

12/25/97

LOCAL_VARIABLES

All the user-defined variables.

PASSWORD

For Basic authentication, contains the decoded password. For example:

password

Note: IBM HTTP Server for AS/400 does not allow access to the PASSWORD variable if authorization is configured which uses AS/400 user profiles and passwords for authentication.

To prevent an application from obtaining an AS/400 user profile password, HTTPD_extract() is sensitive to the type of protect setups that are currently configured. If a protection setup is configured with a password file of %%SYSTEM%% (protection requiring AS/400 user profile password), HTTP_extract() for PASSWORD returns HTTP_PARAMETER_ERROR and sets the value parameter to *CONFLICT. Otherwise, HTTP_extract() returns the appropriate value.

PATH Fully translated path.

PEAKCONNECTIONS

Defines the peak number of connections the server allows. For example:

45

PPATH

Partially translated path.

PROXY_ACCESS

Defines whether the request is a proxy request or not. For example:

NO

PROXY_CONTENT_TYPE

Content-Type header of the proxy request that is made through HTTPD_proxy. When information is sent with the method of POST, this

AS/400E specifications

The IBM AS/400E, now more commonly known as IBM i, is a robust and versatile midrange server that has been designed to provide a comprehensive computing solution for businesses of all sizes. First introduced in the late 1980s, the AS/400 series has undergone multiple enhancements and rebranding, with the AS/400E being one of the notable iterations. This powerful platform is closely associated with IBM's commitment to reliability, scalability, and integrated business solutions.

One of the main features of the AS/400E is its highly integrated architecture that combines hardware and software into a cohesive system. This integration allows for seamless operations, reducing the complexity typically associated with managing disparate systems. The system is powered by IBM's proprietary OS/400 operating system, which has evolved into IBM i, featuring advanced capabilities like object-oriented programming, integrated database management, and security features that are essential for enterprise environments.

A key characteristic of the AS/400E is its robust database support, primarily through the use of DB2 for i. This integrated database management system enables efficient data handling and retrieval, facilitating real-time business analytics and reporting. Furthermore, the platform supports a variety of programming languages, including RPG, COBOL, and Java, making it flexible for developers who require diverse tools for application development.

The AS/400E is also known for its exceptional reliability and uptime, making it a preferred choice for critical business applications in industries such as finance, healthcare, and manufacturing. This reliability is backed by advanced error detection and correction mechanisms, as well as redundancy features that help prevent data loss and minimize downtime.

In terms of scalability, the AS/400E can effortlessly expand to accommodate growing business demands. Organizations can increase processing power by adding more resources without significant disruption. This scalability, combined with the system’s built-in virtualization capabilities, allows businesses to optimize resource usage and streamline operations.

Security is another defining feature of the AS/400E. The platform incorporates various layers of security measures, including user authentication, encryption, and comprehensive auditing capabilities, ensuring that sensitive business data is protected against unauthorized access.

Overall, the IBM AS/400E remains a powerful tool in the enterprise computing landscape, providing businesses with an integrated, reliable, and secure solution for their technological needs. Its enduring popularity is a testament to its capability to evolve with changing business requirements while maintaining its core attributes of high performance and stability.
