![]() SSE works by the browser subscribing to the Web server and keeping the connection up for further data sent. Unlike AJAX, Server-Sent Events (SSE) are an HTML5 technique that allows a server to send data to the browser, without the browser permanently polling for data and therefore reducing unnecessary data overhead. To request data, with AJAX the browser needs to poll for data. Together with browser DOM (Document Object Model) support, it allows dynamic modification of a page without requiring to reload the complete page. The project will now be built when pressing F7 with the internal SEGGER compiler by default. This can be done in the provided example project by simply going to the drop down menu and select 'DebugInternal'. Typical examples are XML files that represent the current state of an application and are therefore subject to change for almost every request.ĪJAX is an acronym for Asynchronous JavaScript and XML. To use the full potential of Embedded Studio it is required to use the internal SEGGER compiler which is based on Clang. Virtual files allow to deliver complete pages that are built when they are requested. Whenever the page is processed by emWeb, the placeholder will be exchanged for the output of a custom application code. The template page can be a simple HTML page with a placeholder for the counter value. Find the project directory examples/bleperipheral/bleapphrs/pca10028/s130/arm5nopacks in the SDK directory, create a file flashplacement.xml with a. ![]() A visitor counter in a page with static content would be one of the simplest use cases. The Common Gateway Interface (CGI) is a replace mechanism that is used in conjunction with a template page. EmWeb supports different techniques to create dynamic pages.
