A Microsoft technology for linking database content to Web pages that predates the development of Microsoft Active Server Pages (ASP) technology. The Internet Database Connector (IDC) is typically used on Internet Information Services (IIS) to allow clients to use Web browsers to access data stored in a Microsoft SQL Server database.
The IDC is a legacy solution for enabling Web browsers to access, read, and modify information in databases, but it is still viable for small environments with limited requirements. The IDC provides excellent performance using open database connectivity (ODBC) versions 3 and later.
The IDC itself is implemented on IIS as an Internet Server API (ISAPI) dynamic-link library (DLL) called Httpodbc.dll that uses ODBC to gain access to SQL databases. To use IDC, you must create the following:
Be sure that you have the DSN of the SQL database being accessed by the Internet Database Connector configured in ODBC as a System DSN, because the Internet Database Connector typically runs not as a user but as part of the operating system. Be sure that execute permissions are configured on the virtual directory where the .idc file is stored on IIS.
