Which MIME types are related to file extension ".rhtml"?
The .rhtml file extension is associated with 2 MIME types:
application/x-erb, text/html+ruby.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .rhtml Files
RHTML files are text documents that mix static HTML with dynamic Ruby code. They use the ERB (Embedded Ruby) engine to process Ruby commands within an HTML framework.
This file type is marked by the MIME types application/x-erb and text/html+ruby. They signal that the file contains both markup and programming logic.
- Dynamic Web Pages: They allow servers to generate pages that change based on user input or data.
- Template Rendering: Ruby code wrapped in tags (usually <% %>) is executed to produce final HTML.
- Web Frameworks: They are commonly used in Ruby on Rails and similar applications.
- Editing Tools: They can be opened with editors like VS Code, Sublime Text, or RubyMine.
When processed by a Ruby interpreter, the embedded Ruby code runs first. Its output then integrates with the HTML and is sent to the browser for display.

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 an RHTML file?
You can open and edit RHTML files using any text-based code editor. Popular choices include Visual Studio Code, Sublime Text, and JetBrains RubyMine, which offer syntax highlighting for both HTML and Ruby. Since the file is plain text, simple programs like Notepad also work, though they lack helpful formatting features.
Why can't I view the RHTML file correctly in my web browser?
Browsers like Chrome or Firefox cannot execute the Ruby code embedded in the file. To view the page as intended, the file must be processed by a web server (such as a Ruby on Rails server) which executes the logic and sends standard HTML to your browser. Opening the file directly usually just displays the raw source code.
What is the difference between .rhtml and .html.erb?
RHTML is the legacy file extension for Embedded Ruby templates. Modern frameworks, particularly Ruby on Rails, have shifted to using the compound extension .html.erb to clearly indicate that the file is HTML content processed by the ERB engine. Functionally, they are handled very similarly.
How do I convert an RHTML file to HTML?
Conversion is typically dynamic and handled automatically by the server's ERB engine. When a user requests the page, the server executes the Ruby code within the <% %> tags and outputs a clean HTML file. To save a static version, you can render the page in a browser via a local server and use the "Save Page As" feature.
What MIME type is used for RHTML files?
These files are generally associated with application/x-erb or text/html+ruby. Correct MIME configuration ensures the server knows to process the file as a script rather than serving it as plain text. You can look up related types on mime-type.com.
Are RHTML files dangerous?
Simply viewing the file in a text editor is safe because it is just code. However, you should be cautious about running .rhtml files from untrusted sources on your web server, as the embedded Ruby code can execute system commands and modify data.
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.
