Hello
I have two web services on two different servers communicating

WS1.asmx
Code:
<%@ WebService Language="VB" Class="WS1" %>

Imports System
Imports System.Web
Imports System.Web.Services
Imports System.Xml.Serialization

Imports System.Net
Imports System.IO

' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
' <System.Web.Script.Services.ScriptService()> _
<WebService(Namespace:="http://www.test.com/ws")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
Public Class WS1
    Inherits System.Web.Services.WebService
    
    Dim IP as String = "192.168.0.174"

    <WebMethod()> _
    Public Function Function1(ByVal s1 As String) As String
        Dim ReturnString As String = ""
        Try
            Dim soap As String = "<?xml version=""1.0"" encoding=""utf-8""?><soap:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/""><soap:Body><Function2 xmlns=""http://www.test.com/ws""><s2>" & s1 & "</s2></Function2></soap:Body></soap:Envelope>"

            Dim req As HttpWebRequest = WebRequest.Create("http://" & IP & "/WS2.asmx")
            req.Headers.Add("SOAPAction", "http://www.test.com/ws/Function2")
            req.ContentType = "text/xml;charset=\utf-8\"
            req.Accept = "text/xml"
            req.Method = "POST"

            Using stm As Stream = req.GetRequestStream()
                Using stmw As New StreamWriter(stm)
                    stmw.Write(soap)
                End Using
            End Using

            Dim response As WebResponse = req.GetResponse()

            Dim responseStream As Stream = response.GetResponseStream()

            Dim s_read As New System.IO.StreamReader(responseStream)
            ReturnString = s_read.ReadToEnd
            s_read.Close()

            ReturnString = Replace(ReturnString, "<?xml version=""1.0"" encoding=""utf-8""?><soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema""><soap:Body><Function2Response xmlns=""http://www.test.com/ws""><Function2Result>", "")
            ReturnString = Replace(ReturnString, "</Function2Result></Function2Response></soap:Body></soap:Envelope>", "")
        Catch ex As Exception
            ReturnString = ex.Message
        End Try
        Return ReturnString
    End Function

End Class
WS2.asmx
Code:
<%@ WebService Language="VB" Class="WS2" %>

Imports System
Imports System.Web
Imports System.Web.Services
Imports System.Xml.Serialization

' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
' <System.Web.Script.Services.ScriptService()> _
<WebService(Namespace:="http://www.test.com/ws")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
Public Class WS2
    Inherits System.Web.Services.WebService

    <WebMethod()> _
    Public Function Function2(ByVal s2 As String) As String
        Dim ReturnString As String = ""
        Try
            ReturnString = "Hello " & s2
        Catch ex As Exception
            ReturnString = ex.Message
        End Try
        Return ReturnString
    End Function

End Class
WS1 calls a function in WS2, my problems is what if the communication between the two servers goes down, is there any way to keep re-trying for a certain time out period (2 minutes suppose) ??

Thank you
