The SSE mechanism was first specified by Ian Hickson as part of the "WHATWG Web Applications 1.0" proposal starting in 2004. [3] In September 2006, the Opera web browser implemented the experimental technology in a feature called "Server-Sent Events".
ComfyUI is an open source, node-based program that allows users to generate images from a series of text prompts.It uses free diffusion models such as Stable Diffusion as the base model for its image capabilities combined with other tools such as ControlNet and LCM Low-rank adaptation with each tool being represented by a node in the program.
To prevent resampling artifacts, it's important that images display at native resolution - one image pixel per device display pixel. To accomplish this, a large number of variations must be created for each screen resolution. An image server can solve that by dynamically adjusting the size of the image according to the user's browser settings.
Proximity—choosing the closest service node—is estimated using a variety of techniques including reactive probing, proactive probing, and connection monitoring. [11] CDNs use a variety of methods of content delivery including, but not limited to, manual asset copying, active web caches, and global hardware load balancers.
The framework is designed to create desktop applications using web technologies (mainly HTML, CSS and JavaScript, although other technologies such as front-end frameworks and WebAssembly are possible) that are rendered using a version of the Chromium browser engine and a back end using the Node.js runtime environment.

Practically it defines how software fetches image tiles from a server. This includes the scale of the image - so a small overview image can be retrieved initially. Zooming and panning are carried out by fetching higher resolution image tiles from server. This means any size of image can be viewed on the Web without downloading it all.
In software development, frontend refers to the presentation layer that users interact with, while backend involves the data management and processing behind the scenes. In the client–server model , the client is usually considered the frontend, handling user-facing tasks, and the server is the backend, managing data and logic.
Web and mobile apps require a similar set of features on the backend, including notification service, integration with social networks, and cloud storage. [9] [10] Each of these services has its own API that must be individually incorporated into an app, a process that can be time-consuming and complicated for app developers. [11]
