How to pass values using http header to another domain?

You can pass information between pages in various ways, some of which depend on how the redirection occurs. The following options are available even if the source page is in a different ASP.NET Web application from the target page, or if the source page is not an ASP.NET Web page:

Use a query string.

Get HTTP POST information from the source page.

The following options are available only when the source and target pages are in the same ASP.NET Web application.

Use session state.

Create public properties in the source page and access the property values in the target page.

Get control information in the target page from controls in the source page.

Can some one please help me with this issue- I am writing exceptions to event log, and my event log is filled with this exception messageSystem.Web.HttpException: Server cannot append header after HTTP headers have been sent.    at System.Web.HttpResponse.AppendHeader(String name, String value)    at System.Web.HttpResponse.AddHeader(String name, String value)    at AddFormPopUp.streamingFiles(String DocID, String FilePath, String FileExtension1)  Here is the code in streamingFiles function.Response.Clear() Dim binReader As New BinaryReader(File.Open((strFileNamePath), FileMode.Open, FileAccess.Read)) binReader.BaseStream.Position = 0 Dim binFile As Byte() binFile = binReader.ReadBytes(Convert.ToInt32(binReader.BaseStream.Length)) binReader.Close() Dim fileStream As New FileStream(strFileNamePath, FileMode.Open, FileAccess.Read) fileStream.Read(binFile, 0, fileStream.Length) Response.AddHeader("content-disposition", "attachment; filename=" & Strfilenameonly) Response.OutputStream.Write(binFile, 0, binFile.Length) fileStream.Close() If Response.IsClientConnected Then Response.Flush() binFile = Nothing Response.Clear() response.end  

 Our IIS server (v7) has the following settings in [Custom HTTP Headers] for our whole site: Pragma: no-cacheCache-Control: private, no-cache, no-store, max-age=0, must-revalidate, post-check=0, pre-check=0X-Powered-By: ASP.NET Out of the whole site, there are some pages that require the "no cache" setting to be removed for them to work properly. This was done manually by our IIS Administrator until recently.  Now we were told that we need to do it programmatically on our end. The following were the code snippets (VB.NET) we have used with no luck in success. Advice is appreciated, Thanks! Method-1Response.Headers.Remove("Pragma")Response.Headers.Remove("Cache-Control")Response.Headers.Add("Cache-Control", "private")Response.CacheControl = System.Web.HttpCacheability.public Method-2Response.ClearHeaders()Response.Headers.Clear()Response.CacheControl = "Public"Response.Cache.SetCacheability(HttpCacheability.Public)Response.Cache.SetAllowResponseInBrowserHistory(True)

Hi All, I am implementing the SharePoint custom fields to pull the data from the SQl Database. This custom field contains two entity picker (like people picker) where the first one will get a record from the Parenet records and second picker has to get the record based on the parent selection. Everything works fine except passing the first entity picker value to second one. Any one has any ideas how to do this? I am trying to use the custom Property in the follwoing way public     RecordPickerData PickerData {     get {     string s =     if (_pickerData == null && String.IsNullOrEmpty(CustomProperty) == false) {     byte[] buffer = Convert.FromBase64String(CustomProperty);     using (MemoryStream stream = new MemoryStream(buffer)) {     BinaryFormatter formatter = new BinaryFormatter(); _pickerData = (   RecordPickerData)formatter.Deserialize(stream); } }     return _pickerData; }     set {     if (value != null) { _pickerData =   value;     using (MemoryStream stream = new MemoryStream()) {     BinaryFormatter formatter = new BinaryFormatter(); formatter.Serialize(stream, _pickerData); CustomProperty =   Convert.ToBase64String(stream.ToArray()); }
