Onclick: refresh + set session

fandt en løsning efter 2:20 timer:

    <%    sprogvalg = Request.ServerVariables("URL") & "?"
        if request.querystring("page") = "" then
        sprogvalg = sprogvalg & replace(Request.ServerVariables("QUERY_STRING"),"language="&request.querystring("language"),"")
        else
        sprogvalg = sprogvalg & replace(Request.ServerVariables("QUERY_STRING"),"&language="&request.querystring("language"),"")
        end if %>
    <td class="TxtSmall">
    <a href="<%=Sprogvalg%><%if request.querystring("page")="" then%>language=dk<%else%><%%>&language=dk<%end if%>"><img border="0" src="../images/dk.gif" width="16" height="10"></a>
    <a href="<%=Sprogvalg%><%if request.querystring("page")="" then%>language=uk<%else%>&language=uk<%end if%>"><img border="0" src="../images/uk.gif" width="16" height="10"></a>
    <a href="<%=Sprogvalg%><%if request.querystring("page")="" then%>language=de<%else%>&language=de<%end if%>"><img border="0" src="../images/de.gif" width="16" height="10"></a>

    </td>

sikkert lidt rodet løsning, men den virker
