What is MIME type "text/vnd.curl.dcurl"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

The MIME type text/vnd.curl.dcurl is a vendor-specific designation. It marks files that contain dynamic Curl scripts—a variant of the Curl programming language used to generate dynamic web content.

These files mix text with code that a Curl engine executes to produce customized responses, much like other server-side scripting languages. The system uses this MIME type to decide how to process the file.

Dynamic Scripting: The file contains executable code meant to run on a server.
Integrated Content: It embeds both layout and logic in one text-based file.
Vendor Specificity: It ensures that only compatible Curl processors handle these files.

Files with this MIME type are typically saved with the DCURL extension. This classification helps systems and applications recognize that the file is not just plain text, but carries instructions for dynamic content rendering.

Usage Examples

HTTP Header

When serving content with this MIME type, set the Content-Type header:


    Content-Type: text/vnd.curl.dcurl

HTML

In HTML, you can specify the MIME type in various elements:


    <a href="file.dat" type="text/vnd.curl.dcurl">Download file</a>

Server-side (Node.js)

Setting the Content-Type header in Node.js:


    const http = require('http');
    
    http.createServer((req, res) => {
      res.setHeader('Content-Type', 'text/vnd.curl.dcurl');
      res.end('Content here');
    }).listen(3000);

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 are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
