What is an SHT file?

An SHT file is an .HTML file that incorporates server-side includes (SSIs) to dynamically generate webpage content. It allows web developers to embed directives within HTML code, which the server processes to include content, such as headers or footers, from other files before delivering the page to a user's browser. This format is still used but has largely been superseded by more modern web technologies, though it remains helpful for maintaining consistent, reusable web content.

More Information

Web servers typically process SHT files to assemble the final HTML page by executing commands like including other files or displaying environment variables. These files are commonly found on websites that require frequent updates or reuse common elements across multiple pages. Developers create these files using text editors as part of their web development workflow.

This file format is advantageous because it reduces redundancy and administration effort, enabling centralized updates to shared content pieces. Despite being less common today, SSIs provide a straightforward approach for small-scale web projects that require modular design and simplicity.

NOTE: SHT files often use the .SHTM or .SHTML extensions.

How to open an SHT file

You can open SHT files with a text editor, such as Microsoft Notepad or Apple TextEdit. For web development purposes, you can use Adobe Dreamweaver, Microsoft Visual Studio Code, or JetBrains IntelliJ IDEA to open and edit SHT files. When the file contains server-side includes, you may need to run it on a compatible web server, such as Apache or Microsoft IIS, to properly process and view the dynamic content.
