.acgi — ActiveX CGI Script
Microsoft · 1996
A proprietary server-side scripting interface for older Windows web servers, enabling dynamic content generation via COM-based languages.
Key Features
- Server-side scripting for dynamic web content.
- Integrates with Windows COM objects and server resources.
- Supports languages like Visual Basic and C++.
- Primarily used with Microsoft IIS web server.
Best For
- Maintaining legacy web applications on older IIS servers.
- Situations requiring deep integration with Windows COM components.
- Server-side scripting on specific Windows-based hosting environments.
Less Ideal For
- Cross-platform development or non-Windows servers.
- Modern web application development.
- Performance-critical applications requiring efficient execution.
- Environments where open standards are preferred.
Common Use Cases
- Generating dynamic HTML content based on user requests.
- Interacting with databases on the server.
- Performing server-side logic for web applications.
- Customizing web server responses.
How to Open It
- ACGI scripts are not typically opened directly by end-users; they are executed by a web server.
- To view or edit the script's source code, you would need a text editor or an Integrated Development Environment (IDE) that supports the scripting language (e.g., Visual Studio for older versions).
- Ensure the script is deployed on a compatible web server (like IIS) and configured correctly to be processed.
What is a .acgi file?
ACGI (ActiveX CGI) is a scripting interface used on Windows-based web servers, primarily Microsoft Internet Information Services (IIS). It allows web pages to execute server-side code written in languages compatible with Microsoft's COM (Component Object Model) technology, such as Visual Basic or C++. This enables dynamic content generation and interaction with server resources. However, it has largely been superseded by more modern technologies like ASP.NET, making it a less common choice for new web development projects.

Frequently Asked Questions
No, ACGI is considered a legacy technology and has been largely replaced by ASP.NET and other modern web development frameworks.
No, ACGI is a Microsoft-specific technology that relies on Windows COM components and is not compatible with Linux or other non-Windows server environments.
CGI (Common Gateway Interface) is a standard protocol for web servers to execute scripts, while ACGI (ActiveX CGI) is Microsoft's proprietary extension that leverages ActiveX and COM technology for server-side execution on Windows.
Technical Details
ACGI scripts function as COM objects on the server. When a request for an ACGI script is made, the web server instantiates the COM object, passes request information, and executes the script's methods. The script's output is then returned to the browser. It relies heavily on the Windows environment and COM infrastructure.
