NetworkData interface

Contains information about the network streams for a synchronization.

Visual Basic syntax

Public Interface NetworkData

C# syntax

public interface NetworkData

Members

All members of NetworkData interface, including all inherited members.

Name	Description
GetHTTPHeaderValue method	Returns the value of the last header received by the server with the supplied name.
GetHTTPHeaderValues method	Returns all the header values received by the server associated with the supplied name.
ClientCertificates property	Returns the existing connection to the MobiLink consolidated database.
HTTPHeaders property	Returns a dictionary that maps header names to a list of header values.
IsEndToEndEncrypted property	Determines if this synchronization is end-to-end encrypted.
IsHTTP property	Determines if the synchronization uses HTTP or HTTPS.
IsTLS property	Determines if this synchronization uses TLS.

Remarks

This interface is useful when authenticating against another server in the enterprise that uses the client-side certificate and HTTP headers.

To enable a collection of network stream data, add collect_network_data=1 to your -x switches. This option adds additional per-sync memory overhead to store the data. When using TLS or HTTPS, the server asks the client to send a certificate during the TLS handshake, incurring a time and network cost.

You can obtain a NetworkData object by invoking the NetworkData method of the DBConnectionContext interface. When using HTTP or HTTPS, it contains the header data for the last HTTP request received by the server before the authenticate scripts are invoked.

Example

The following example illustrates how to get a NetworkData object from the DBConnectionContext object, and output the data.

using iAnywhere.MobiLink.Script;
using System.Collections.Generic;
using System.Security.Cryptography.X509Certificates;

public class OrderProcessor {
    DBConnectionContext _cc;

    public OrderProcessor( DBConnectionContext cc ) {
        _cc = cc;
    }

    public void AuthUser() {
        NetworkData nd = _cc.NetworkData;
        if( nd != null ) {
            if( nd.IsHTTP ) {
                PrintLn( "http" );
                string user_agent = nd.GetHTTPHeaderValue( "user-agent" );
                PrintLn( "  user-agent: " + user_agent.Substring( 0, user_agent.IndexOf( '/' ) ) );
            } else {
                PrintLn( "no http" );
            }
            if( nd.IsTLS ) {
                PrintLn( "tls" );
                X509Certificate2Collection certs = nd.ClientCertificates;
                if( certs != null ) {
                    PrintLn( "  client-side cert:" );
                    int n = 1;
                    foreach( X509Certificate2 x509 in certs ) {
                        PrintLn( "    cert " + n++ );
                        PrintLn( "      Subject: " + x509.SubjectName.Name );
                        PrintLn( "      Issuer: " + x509.IssuerName.Name );
                    }
                } else {
                    PrintLn( "  no client cert" );
                }
            } else {
                PrintLn( "no tls" );
            }
            if( nd.IsEndToEndEncrypted ) {
                PrintLn( "e2ee" );
            } else {
                PrintLn( "no e2ee" );
            }
        } else {
            PrintLn( "NULL networkdata" );
        }
    }
