Setting temporary file location

Unlike standard ASP.NET HtmlInputFile control, AJAX Uploader does not read the entire uploaded file into memory. It streams the data into a temporary file while the data is received. For this reason, you must specify a temporary file location. You should ensure that the ASPNET user (NetworkService in Windows Server 2003) has read/write permission to this specified folder.

You can easily specify the temporary file location using the following two methods:

1. Using TempDirectory property 
   
   

   For example:

   <CuteWebUI:Uploader id="Uploader1" TempDirectory="~/UploaderTemp" runat="server"></CuteWebUI:Uploader>
2. Setting temporary file location in web.config 
   
   Add the following tag into the <appSettings> element of your application web.config file:
   
   <add key="CuteWebUI.AjaxUploader.TempDirectory" value="~/UploaderTemp"/>

   In web farm environments, the Url that you specify must map to a central location, which is saved to by all servers in the farm. This can be done using a virtual directory that maps to a common shared folder on the network.

   <add key="CuteWebUI.AjaxUploader.TempDirectory" value="\\shareserver\temp"/>
