ASP.NET MVC 3: server cannot add header after sending HTTP headers

We are busy updating the ASP.NET MVC 2 application using the 3.5 environment for the ASP.NET MVC 3 application running on platform 4.0.

There is a page that throws an exception when it is brought closer using the return button to the browser. To support the back button on this page, we have implemented a system that requests the results for this page again when you return to the page. I do not have clear directions where to look for the problem, since I always find an error

Server cannot append header after HTTP headers have been sent.

Using stacktrace

at System.Web.HttpResponse.AppendHeader(String name, String value)
at System.Web.HttpResponseWrapper.AppendHeader(String name, String value)
at System.Web.Mvc.MvcHandler.AddVersionHeader(HttpContextBase httpContext)
at System.Web.Mvc.MvcHandler.ProcessRequestInit(HttpContextBase httpContext, IController& controller, IControllerFactory& factory)
at System.Web.Mvc.MvcHandler.<>c__DisplayClass6.<BeginProcessRequest>b__2()
at System.Web.Mvc.SecurityUtil.<>c__DisplayClassb`1.<ProcessInApplicationTrust>b__a()
at System.Web.Mvc.SecurityUtil.<GetCallInAppTrustThunk>b__0(Action f)
at System.Web.Mvc.SecurityUtil.ProcessInApplicationTrust(Action action)

at System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContext httpContext, AsyncCallback callback, Object state)

at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Why are HTTP headers already sent?

Thanks in advance, IvanL

EDIT: , . , , . , MVC2:

[HttpPost, ValidateInput(false)]
public void SearchResultOverview(SearchResultViewModel model, string searchUrl)
{
    if (!string.IsNullOrEmpty(searchUrl))
    {
        searchUrl = searchUrl.Replace("SearchPartial", "SearchPartialInternal");

        //NOTE MVC 3
        HttpContext.Server.TransferRequest(searchUrl, true);

        //NOTE MVC 2
        //System.Web.HttpContext.Current.RewritePath(searchUrl, false);

        //IHttpHandler httpHandler = new MvcHttpHandler();
        //// Process request
        //httpHandler.ProcessRequest(System.Web.HttpContext.Current);
    }
}

TransferRequest, , Performs an asynchronous execution of the specified URL and preserves query string parameters. (http://msdn.microsoft.com/en-us/library/system.web.httpserverutility.transferrequest.aspx)
