About .lasso Files
LASSO files are plain text files used for creating database-driven web pages. They contain code written in the Lasso scripting language and often mix HTML with SQL-like commands.
These files use the MIME type text/x-lasso, which signals that the file holds text-based instructions for generating dynamic web content.
- Web Applications: They generate pages that interact with databases.
- Server-Side Scripting: They run on web servers equipped with Lasso engines.
- Plain Text Format: They can be opened and edited in text editors like Notepad++ or Sublime Text.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
How do I open and edit a .lasso file?
You can open and edit .lasso files using any standard text editor or code editor. Popular choices include Notepad++, Sublime Text, Visual Studio Code, or even the built-in Notepad on Windows. These tools allow you to view the source code and modify the HTML and Lasso scripting tags contained within the file.
How do I run a .lasso file in my web browser?
You cannot run a .lasso file directly by double-clicking it; it requires a web server with the Lasso Server engine installed. When a browser requests the file from a properly configured server, the server processes the script and sends back standard HTML. If you try to open it locally without a server, you will likely see the raw code instead of the web page.
What is the correct MIME type for serving .lasso files?
The primary MIME type associated with Lasso files is text/x-lasso. Web servers must be configured to associate the .lasso extension with this MIME type so that the server knows to execute the script rather than serving it as a static file. You can look up similar server-side text types on mime-type.com.
Why does my browser display code instead of a webpage when opening a .lasso file?
This usually happens because the web server is not configured to recognize the .lasso extension or the Lasso Server middleware is not running. Without the engine to process the server-side tags, the web server treats the file as plain text (often defaulting to text/plain) and displays the raw source code to the user.
Can I convert a .lasso file to HTML?
You cannot simply convert the file format because .lasso files contain dynamic logic that must be executed to produce content. However, if you run the file through a Lasso-enabled server, you can save the output of the page as an .html file via your browser's Save Page As feature. This captures the static result but loses the underlying database connectivity.
What is the Lasso scripting language used for?
Lasso is a server-side scripting language primarily designed for building data-driven web applications. It is historically known for its strong integration with FileMaker Pro databases, allowing developers to easily create web interfaces for FileMaker data, though it also supports MySQL and other data sources.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
