Custom validaton to put file size limit in file upload control in asp.net

Use custom validator as follow :-

  <asp:CustomValidator ID="NewPasswordCustomValidator" runat="server" Text="File Size Limit exceed !! Only 20 MB is allowed"
                                                ToolTip="FileSize should not exceed 4 MB" ControlToValidate="FileUpload1" ClientValidationFunction="setUplaodButtonState"
                                                Display="Dynamic" ValidationGroup="submit" ErrorMessage="File Size Limit exceed !! Only 20 MB is allowed"></asp:CustomValidator>


Then make one javascript function to put limit on size upto 20mb

   function setUplaodButtonState(oSrc, args) {

            var maxFileSize = 20480000 // 20MB -> 20000 * 1024 //
            var fileUplaod = $("#<%=FileUpload1.ClientID %>");

            if (fileUplaod.val() == '') {
                args.IsValid = false;
            }
            else {
                if (fileUplaod[0].files[0].size < maxFileSize) {
                    args.IsValid = true;
                } else {
                    alert('File Size is' + ((fileUplaod[0].files[0].size / 1000) / 1024).toFixed(2) + 'MB !! Only size upto 20 MB is allowed');
                    args.IsValid = false;
                }
            }
        }

Ip Sec Internet Security Basic Structure

The IPsec suite is an  open standard . IPsec uses the following  protocols  to perform various functions: Authentication Headers (AH)  provide connectionless  integrity  and data origin  authentication  for IP  datagrams  and provides protection against  replay attacks . Encapsulating Security Payloads (ESP)  provide  confidentiality , data-origin  authentication , connectionless  integrity , an anti-replay service (a form of partial sequence integrity), and limited traffic-flow confidentiality. Security Associations (SA)  provide the bundle of algorithms and data that provide the parameters necessary to AH and/or ESP operations. The  Internet Security Association and Key Management Protocol  (ISAKMP) provides a framework for authentication and key exchange, with actual authenticated keying material provided either by manual configuration with pre-shared keys,  Internet Key Exchange  (IKE and IKEv2),  Kerberized Internet Negotiation of Keys  (KINK), or IPSECKEY  DNS records .
