Retrieves the last modified string of the corresponding file for an IHttpFileInfo interface.
virtual PCSTR GetLastModifiedString(
VOID
) const = 0; This method takes no parameters.
A pointer to a string that contains the last modified date and time.
The GetLastModifiedString method retrieves a string that contains the date and time that a file currently referenced by an IHttpFileInfo interface was last modified. The GetLastModifiedString method is similar to the IHttpFileInfo::GetLastModifiedTime method, except that the GetLastModifiedString method returns only a string, whereas the GetLastModifiedTime method returns a FILETIME structure that you can use for comparisons.
The following code example demonstrates how to use the IHttpContext::GetFileInfo method to create an HTTP module that retrieves a pointer to an IHttpFileInfo interface. The example then calls the GetLastModifiedString method to retrieve a string that contains the last modified date and time. Finally, the example displays this information to a Web client.

Your module must export the RegisterModule function. You can export this function by creating a module definition (.def) file for your project, or you can compile the module by using the /EXPORT:RegisterModule switch. For more information, see Walkthrough: Creating a Request-Level HTTP Module By Using Native Code.
You can optionally compile the code by using the __stdcall (/Gz) calling convention instead of explicitly declaring the calling convention for each function.
