Hi i solved this error which was really a show stopper.

Just add <Seriliazable> _ on top of all class where you are using sessions.

It must work

this error nearly killed me. i developed a webpart for sharepoint, adding the following line to <httpmodules> in web.config fixed the problem for me:

add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /

Hi,

I have faced the simillar problem but i fixed it may be because i left some buggy code in there or response. write or something.. But this looks something new to me i wanted to know how this solution fixes it or what is happening when u do this?

Jaxom:

A simple soution i found to this whole problem was to declare a Session State Variable in the PageLoad method of the page. The problem went away immediately...

protected void Page_Load(object sender, EventArgs e)
{

if (IsPostBack == false)
{

if (Session["Dummy"] == null)
{

Session[
"Dummy"] = 0;
}

...

}

erzki:
I'm developing in a content management system (CMS) called EPIServer, therefore I cannot post all code here. The problem only occur on pages in the CMS system. When I place the code in a seperate file with no CMS it works fine. Maybe you cannot help me because I'm using this CMS system, but it worked very well in the July CTP, so there must have been some changes with the parser or what is being sent in the xml.

The problem is due to EPiServer's Url Rewriting.

The simple solution is to use a control adapter to sort the action value of the form.

Hi,

I had the same problem (AJAX + url rewriting) and I implemented a simple response filter:

using System;
using System.Text;
using System.Text.RegularExpressions;
using System.IO;
using System.Web;

public class AjaxPageFilter : Stream
{
    Stream          responseStream;
    long            position;
    StringBuilder   responseHtml;

    public AjaxPageFilter(Stream inputStream)
    {
        responseStream = inputStream;
        responseHtml = new StringBuilder ();
    }

    public override bool CanRead
    {
        get { return true;}
    }

    public override bool CanSeek
    {
        get { return true; }
    }

    public override bool CanWrite
    {
        get { return true; }
    }

    public override void Close()
    {
        responseStream.Close ();
    }

    public override void Flush()
    {
        responseStream.Flush ();
    }

    public override long Length
    {
        get { return 0; }
    }

    public override long Position
    {
        get { return position; }
        set { position = value; }
    }

    public override long Seek(long offset, SeekOrigin origin)
    {
        return responseStream.Seek (offset, origin);
    }

    public override void SetLength(long length)
    {
        responseStream.SetLength (length);
    }

    public override int Read(byte[] buffer, int offset, int count)
    {
        return responseStream.Read (buffer, offset, count);
    }

    public override void Write(byte[] buffer, int offset, int count)
    {
        string finalHtml = System.Text.UTF8Encoding.UTF8.GetString(buffer, offset, count);

        // Transform the response
        string formAction = Util.OriginalRequestUrl;
        if (!String.IsNullOrEmpty(formAction))
        {
            finalHtml = Regex.Replace(finalHtml, "\\|\\d+\\|formAction\\|\\|[^\\|]+\\|",
                "|" + formAction.Length.ToString() + "|formAction||" + formAction + "|",
                RegexOptions.IgnoreCase);
        }

        // Write the response
        byte[] data = System.Text.UTF8Encoding.UTF8.GetBytes(finalHtml);
        responseStream.Write(data, 0, data.Length);   
    }
}

You should replace "Util.OriginalRequestUrl" with your code.

This filter can be attached in some HttpModule for example like this:

    public class UrlRewriter : IHttpModule
    {
        public UrlRewriter()
        {
        }

        public void Dispose()
        {
        }

        public void Init(HttpApplication application)
        {
            application.BeginRequest += new EventHandler(application_BeginRequest);
            application.ReleaseRequestState += new EventHandler(InstallResponseFilter);
        }

        void application_BeginRequest(object sender, EventArgs e)
        {
            HttpContext context = HttpContext.Current;

            // original URL
            string url = context.Server.UrlDecode(context.Request.Url.ToString());

            // store original URL
            Util.OriginalRequestUrl = url;

            // ...
        }

        private void InstallResponseFilter(object sender, EventArgs e)
        {
            HttpResponse response = HttpContext.Current.Response;

            if (response.ContentType == "text/plain")
                response.Filter = new AjaxPageFilter(response.Filter);
        }
    }

Hope that helps.

What code should I use in place of "Util.OriginalRequestUrl" ??
