remove session when hyperlink clicked

hi guys,
i wonder is it possible to remove my session when a hyperlink clicked? * pls note that after session removed will redirect to the corresponding NavigateURL.
<asp:DataList ID="dl_Product" runat="server" DataKeyField="PID" > <ItemTemplate> <asp:HyperLink ID="hl_clear" runat="server" NavigateUrl="product_detail.aspx?ID=12345" OnClientClick="remove session here??!!"></asp:HyperLink> </ItemTemplate> </asp:DataList>
