Write an OnFindStream event handler to supply the WebSnap application with the contents of a file given its name. This event is particularly useful for applications that use "logical" files that do not exist physically on disk. When the WebSnap application tries to locate a file, the locate file service generates this event, along with an OnFindTemplateFile. One of these event handlers must be provided in order for the application to use the requested file.
