Question

Had a headace trying to get this to work,

im trying to set up my ASP.NET web service to handle a custom header sent from iPhone.

Literally, sounds simple, all I am trying to do is retrieve a string value from a header that is sent from the iPhone to the web service.

So far, the iPhone has no issues sending “test” as a value to the following header “testHeader”

in pseudo, how is it possible to

string s = mywebservice.soapHeader.title = "testHeader"

any ideas please.

I have defined my class definition for the soap header which has a string attribute, but im having no luck trying to get that string attribute the value of this custom header!

cheers in advance

Take a look a this :
Digging into SOAP Headers with the .NET Framework

you should have a class in the web service that inherits SoapHeader

Public Class PriorityHeader
    Inherits SoapHeader
    Public Priority As PriorityLevels
    Public Enum PriorityLevels
        LowPriority
        MediumPriority
        HighPriority
    End Enum
End Class 

Then markup you web method like this :

<WebMethod(), SoapHeader("PriorityLevel", Direction:=SoapHeaderDirection.InOut,   Required:=False),SoapDocumentMethod()>
Public Function YourMethod(ByVal quantity As Integer) As DateTime

And after this you can access the SOAP Header like this :

 If PriorityLevel Is Nothing Then
        PriorityLevel = New PriorityHeader()
        PriorityLevel.Priority = _
            PriorityHeader.PriorityLevels.MediumPriority
    End If
    Select Case PriorityLevel.Priority
    bla bla bla bla bla
