Call a ASPX from two different ASPX Pages

I have three ASPX Pages. The ASPX Page which get called from the two other Page is a Page where i can Upload files.

I call that Upload-Page from the other two Pages with JavaScript:

 function UploadFax_Click() {
             var grid = ISGetObject("WebGrid1");
             var curSelObj = grid.GetSelectedObject(); // get selected object
             var row = curSelObj.GetRowObject(); // get the WebGridRow object
             if (row.Type == "Record") {
                 var s_id = row.KeyValue
            }
            window.location = '../Admin/UploadFax.aspx?suppid=' + s_id;
         }

Then on the Upload-Page i get the QueryString:

 If Not IsPostBack And Len(Request.QueryString("suppid")) > 0 Then
        If Not Request.QueryString("suppid") Is Nothing Then
            Session("suppid") = Request.QueryString("suppid")
        End If
    End If

What i need is that if i call the Upload-Page from one of the two Pages the functions of the Upload-Page should be restricted. For Example: If i call the Upload-Page then Checkbox.Disabled = true and from the other page Checkbox should be enabled.

My idea was to send a second parameter from that page, then get the parameter with Request.QueryString and then use if/else to enable oder disable that checkbox.

Question is, is there another, better possibility to do that what i want? If yes how can i do that?

Using QueryString may cause a security violation , Why not you use Session parameter,

when you Call it from the First Page then set 

Session("IsCalled")="1"

in the second page load check 

IF Not Session("IsCalled") Is Nothing AndAlso Session("IsCalled")="1" Then
   CheckBox1.Enabled=False
End If

and Vise Versa in the first page load.

You can check the Request.UrlReferrer and dance from it:

Dim restrictedAccess As Boolean = Not IsNothing(Request.UrlReferrer) AndAlso
        Request.UrlReferrer.AbsolutePath.IndexOf("/Original.aspx", StringComparison.InvariantCultureIgnoreCase) >= 0

Checkbox.Disabled = Not restrictedAccess
