Prevent duplicate insert without session

im working on sharepoint 2010 (using visual webpart) is there any way to prevent duplicate

insert in a list when page is refreshed using F5, without using session



The sharepoint "way" is usually to redirect to the list view page after you have inserted a new item:

So the web part posts to some page, with a Source parameter:


Then after the save event, redirect

SPUtility.Redirect(base.ListEditPageLayoutsRelativeUrl, SPRedirectFlags.RelativeToLayoutsPage, this.Context);

Take a look at the FormDigest control and see if that will do what you need.
