Master HTTP Requests with 4D Request Handlers

In today’s web-driven world, servers process an overwhelming number of requests. Efficiently analyzing, counting, interpreting, and rerouting these requests is essential, especially when applying MVC principles.

In 4D 20 R8, with the introduction of HTTP Request Handlers on the 4D HTTP Server, you can define accurately which business logic you want to trigger regarding specific URLs patterns.

Main advantages of this feature are:

  • Offering more granularity in implementing the code handling received requests. This business logic can be split in several classes. Forget extensive Case of statements in the On Web Connection database method.
  • Allowing a redirection on a Qodly page which opens up new perspectives to extend 4D application on the web

 

This powerful feature unlocks many possibilities, as detailed below. Keep reading to learn more and work with concrete examples.

Energize your Web applications with the OutgoingMessage Class

In today’s digital world, a smooth and intuitive user experience is key to any web application’s success. A critical part of this experience is providing users with easy access to various resources—whether documents, images, or other data types. To make this possible, your server must manage and deliver different content formats efficiently.

With 4D’s 20 R7 new REST server feature, managing diverse content delivery is now easier than ever. Previously, the REST server could only return scalar, entity, or entity selection data. Now, it can deliver full web content directly—content ready for a browser to handle.

Downloading files or receiving binary data from the REST server is now straightforward, thanks to the new OutgoingMessage class. With it, you can easily customize responses to suit your needs.

Read on to explore how the OutgoingMessage class can enhance your application!

Qodly Studio for 4D: Dynamic User Interfaces with Page States

With 4D 20 R6, Qodly Studio for 4D introduced an exciting new feature: Page States. Perhaps you’ve already come across our previous post, but let’s explore what makes this feature so valuable for dynamic UIs.

Imagine UIs that adapt instantly to different user steps or contexts.

Here are some common use cases where Page States shine:

  • Enable or disable components based on user actions (e.g., activate the “Save” button only when all mandatory fields are filled).
  • Switch between light and dark modes with a simple toggle.
  • Restrict access to actions (read, update, etc.) based on user privileges.

    Permissions: Inspect Session Privileges for Easy Debugging

    Today, you can benefit from a powerful feature to filter access to data, which is essential for preventing malicious access to your application.
