Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see About Dynamic Properties.
Remarks
Applets do not support version information supplied as part of the URL.
If a,b,c,d are all set to -1 (#Version=-1,-1,-1,-1), the component is downloaded from the server if the release date is later than the installation date on the client computer. If the component is installed on the client computer and the release date is the same or earlier than the installation date, only an HTTP header transaction occurs.
The URL of the component cannot be a local path.
