In the modern era of dynamic JavaScript frameworks (React, Vue, Angular) and server-side languages like PHP and Python, you might stumble upon an unfamiliar file extension while digging through old web servers, legacy intranet portals, or archived projects: .shtml .

When you encounter this file type, a common troubleshooting command or search query emerges: But what does this mean? Is it different from viewing regular HTML? And why would you need a "full" view?

Run this, and you will see the printed to your terminal. Part 4: How to View the “Full Raw” SHTML Source (Unparsed) If you need to see the original SHTML code including the #include tags (for debugging or learning), do this: Method A: View Source in Browser (Caveat) If the server is configured to parse SHTML, pressing Ctrl+U (View Source) will show you the rendered output —not the original SHTML. This is because the server sends only the final HTML to the client.

Use a curl command to fetch the raw file from a misconfigured server:

RemoveHandler .shtml AddType text/plain .shtml Now visiting page.shtml in a browser will show the raw directives. Disable this after debugging. Part 5: Common Errors When Trying to “View SHTML Full” When you search for this term, you are likely encountering one of these three errors. Here is how to fix them.

with open('index.shtml', 'r') as f: raw = f.read() print(parse_shtml(raw, './'))

<!--#include virtual="header.html" --> Main content here. The browser treats the SSI as an HTML comment (which it technically is) and ignores it. You want to after the server processes the includes. Problem B: The Page Renders, but Includes are Missing If your web server supports SSI but the file paths are wrong, you might see a broken layout (e.g., no navigation bar, no footer). To diagnose this, you need to view the full source code that the server actually sent —not the DOM tree, but the raw HTML output. Problem C: Security or Forensics Audit If you are auditing an old web application, you might want to see the full, unparsed source of an SHTML file (including its SSI directives) to understand how the page was constructed. This is the opposite of problem A—you want to see the template, not the final product.
