The following table shows the Web Server functions with a description of the purpose of each.
| Programming element | Description |
|---|---|
| AddHeader | This callback function is provided by the Web Server. ISAPI filters call this function to add an HTTP header to the outgoing response. |
| AddResponseHeaders | This callback function is provided by the Web Server. ISAPI filters call this function to add a header to the HTTP response. |
| AllocMem | This callback function is provided by the Web Server. ISAPI filters call this function to allocate memory from the process heap to a buffer. |
| GetExtensionVersion | This function is called by the Web Server when the ISAPI extension is first loaded for the function name defined by the header. |
| GetFilterVersion | This function is the first entry-point function called by the Web Server on your ISAPI filter, and must be present for the filter to work properly. |
| GetHeader | This callback function is provided by the Web Server. ISAPI filters call this function to retrieve a header from the Web Server. |
| GetServerVariable (ISAPI Extensions) | This callback function is an application-defined function. ISAPI extensions call this function to retrieve information about an HTTP connection or about the Windows CE Web Server itself. |
| GetServerVariable (ISAPI Filters) | This callback function is an application-defined function. ISAPI filters call this function to retrieve information about an HTTP connection or about the Windows CE Web Server. |
| HttpExtensionProc | This function is an application-defined function. It is the main entry point for an ISAPI extension called by the Web Server. |
| HttpFilterProc | This function is called whenever a notification event for which the filter has registered (in GetFilterVersion) occurs. |
| ReadClient | This callback function is an application-defined function. ISAPI extensions call this function to read data from the body of the client's HTTP request. |
| ServerSupportFunction (ISAPI Extensions) | This callback function is provided by the Web Server. This callback function is supplied in the EXTENSION_CONTROL_BLOCK that is associated with the current HTTP request. |
| ServerSupportFunction (ISAPI Filters) | This callback function is provided by the Web Server. ISAPI filters call this function to accomplish a wide variety of tasks. |
| SetHeader | This callback function is an application-defined function. ISAPI filters call this function to change or delete the value of a header. |
| TerminateExtension | This function is an application-defined function. The Web Server calls this function immediately before it unloads the ISAPI DLL. |
