To resume a stored session ITP/OnLine Server comes with a page called modelresume.aspx (modelresume.jsp). In the default implementation, this page asks the user for a file containing a stored session, which will be uploaded to ITP/Server. ITP/Server will use the file to restore it in a new ITP session, which will be used to resume the stored session. After this the user will be forwarded to the ITP/OnLine form, which was originally shown when the Suspend was performed.
Both the modelresume.aspx (modelresume.jsp) page and the ResumeSession script are marked as exit points, so they can be modified. Instead of asking the user to upload a file these exit points could e.g. let ITP/Server retrieve the stored session file.
ITP/Server also contains the exit point script SessionResumed, which is called after a suspended session has been restored. Refer to ITP/Server: OnLine exit points for more information on these scripts.
