Hi.

 I'm developing a web-site, that uses SWFUpload for multiple files upload to the server. Page, that uploades files, is accessable only to registered user. Authentication is done via web-forms (authentication mode="Forms" in Web.config). Flash uploades files to special web page - upload.aspx. In IE everything works great, but Flash player in non-IE browser (in Firefox, for example) does not send any cookies to upload.aspx. Because of it no sesion and no authentication information is available in this page.

 I can pass all the information, necessary for uploading, in GET-parameters, which upload.aspx recieve. But this is a serious security hole and I don't want to expose session information. I can pass session identifier in GET-request. But the question is the following: how can I restore session information from the session identifier? How can I make HttpContext.Current.User point to currently logged in user in this case?

I have a text input to get a 'roomID' and an ASP button that calls an 'enterRoom' function:

roomID:<asp:TextBox runat="server" ID="roomID"></asp:TextBox>
                <asp:Button ID="Button1" runat="server" Text="Enter Room!" OnClick="enterRoom" />

    <script runat="server">
        Sub enterRoom(ByVal sender As Object, ByVal e As System.EventArgs)
            Server.Transfer("users/room.aspx?roomID=" & Request.Form("roomID"))
        End Sub
    </script>

 Request.UrlReferrer is not working. can any one  help me to find the previous page url ?

 Hi People, How are you all doing?

I have 2 pages one is SearchPage & It has DropDowns, textboxes to specify the search criteria. From the search result the user is redirected to another page when he clicks the hyperlink in the search result  where he fills in the information and again redirected to SearchPage. Now the SearchPage is posted back with no state i just want to retain the search criteria and display when user comes back. Please give me some suggestion how to get this done. I've used ViewState to save the values and check them in Page_Load but they are null.   

Thanks

Abid

 Update: I've come up with this code. But the problem is The values are being retained but the Button_Click event is not being handled properly. When i Check the code even after this "DropDownList1.SelectedValue = Session["Name"].ToString();" DownList1.SelectedValue is EMPTY"" samw with DropDownList2 . please Suggest something

    protected void Page_Load(object sender, EventArgs e)
    {
        if (IsControlsEmpty())
        {
            if (SessionExist())
            {
                DropDownList1.SelectedValue = Session["Name"].ToString()

Why do controls value not persist when returning to a page (e.g. via browser back button)?  If I set control values without utilizing a post back the controls will maintain their last value when I return to the page.  If I set a control value and then call a post back, the control value is reset to the default value when returning.

I have many pages with a gridview, and a textbox which is used to filter the gridview contents.  I set the filter textbox, filter the gridview (postback), go to another page, and when I return to the gridview page (via back button), my filter textbox is reset empty, and the gridview is the original (unfiltered) data.

What concept am I missing here?

Thanks in advance...

The statement is correct:

<asp:HyperLink ID="HyperLink2" runat="server" Text

Hi All-

I'm using Request.PathInfo to response.redirect as user to a different page ( based on the content after .aspx ).  It redirect just fine however, once redirected, the page loses all content from the master page and the CSS link.  I've searched and can't find an answer. 

Does anyone have a solution for this?
