Protocol Handlers play a crucial role in how web browsers and devices interact with specific types of links, such as ICS (iCalendar) links. ICS links, often seen as webcal or ical links, are used to add calendar events directly to a user's personal calendar application. When a user clicks on an ICS link, their browser or device must recognize the protocol (webcal, ical) and handle the request correctly, either by downloading the file or opening it in a compatible calendar application.
This guide will help you understand how ICS links work on Tithely Sites, how different devices and browsers handle these links, and what you can do to ensure a smooth user experience.
What Are ICS Links?
ICS (Internet Calendar Scheduling) files are a standard format used to share calendar events. They contain event details like date, time, location, and description, and are supported by most calendar applications, including Google Calendar, Apple Calendar, and Microsoft Outlook.
How Protocol Handlers Work
A protocol handler is a mechanism that allows web browsers to recognize and process specific types of links or protocols. In the context of ICS links, the protocols in question are "webcal" and "ical." When a user clicks on an ICS link on a Tithely Site, the browser checks if there is a registered protocol handler for the link type:
webcal:// - This protocol is designed to open calendar files directly in a web-based calendar service or application.
The link associated with "Subscribe to Calendar" on Tithely Sites is a webcal:// link, this link will be opened in the appropriate application or service determined by your browser/device. If not yet set, the user may be prompted to download the file or select an application manually.
How Different Devices and Browsers Handle ICS Links
The handling of ICS links can vary significantly based on the device and browser a user is using:
1. Desktop Browsers:
- Google Chrome: Chrome generally prompts users to download the ICS file. However, users can configure Chrome to automatically open ICS files with their default calendar application.
- Mozilla Firefox: Firefox gives users the option to open the file with an installed calendar application or save it locally.
- Microsoft Edge: Edge typically behaves similarly to Chrome, offering a download prompt and sometimes suggesting opening the file in a web-based calendar.
2. Mobile Devices:
- iOS (Safari): On iOS devices, ICS links will usually open directly in the Apple Calendar app, allowing users to add the event with a single tap.
- Android (Chrome, Firefox): Android devices often prompt the user to choose an app to open the ICS file, such as Google Calendar or another calendar app installed on the device.
