We are currently using v2.5 Screen Connect (formerly Elsinore) and (oh long ago) made a Windows support client that would create a http post and send to a ashx web handler to create the session and return the session values to execute the local (bundled) ScreenConnect guest Client. We are attempting to do the same in v6.3 and it appears things have gotten a bit more complicated. The v2.5 code to create the session (server-side) is below. I am hoping for some assistance in "translating" this to version 6. With the addition of Extensions and all of the other "new" integration possibilities, I cannot seem to find a "modern" rendition of this! Thanks for any advice in advance!

<%@ WebHandler Language="VB" Class="CreateSession" %>

Imports System
Imports System.Web

public class CreateSession
Implements IHttpHandler

Public Sub ProcessRequest(ByVal context As HttpContext) _
Implements IHttpHandler.ProcessRequest

Dim sCode as String = Context.Request("Code")

Dim objSessionMgr As Elsinore.ScreenConnect.ISessionManagerChannel _
= Elsinore.ScreenConnect.ServerExtensions.SessionManagerChannelFactory.CreateChannel

Dim objSession As Elsinore.ScreenConnect.Session

Dim uidSession As Nullable(Of Guid) = objSessionMgr.GetSessionID(Elsinore.ScreenConnect.InvitationType.Code, sCode)

If uidSession.HasValue Then objSession = objSessionMgr.GetSession(uidSession)

If objSession Is Nothing Then

objSession = objSessionMgr.CreateSession(Elsinore.ScreenConnect.InvitationType.Code, sCode, "Name")
uidSession = objSession.SessionID

objSessionMgr.TransferSession(objSession.SessionID, "Name")

End If
'\\ Return the following 5 pipe-separated values:
'\\ Session Code, SessionID (UID), Encryption Key, Session Title, Session Host
Context.Response.Write(sCode & _
"|" & objSession.SessionID.ToString & _
"|" & Convert.ToBase64String(objSession.EncryptionKey) & _
"| Header Name" & _
"|" & objSession.Host)
End Sub

Public ReadOnly Property IsReusable() As Boolean _
Implements IHttpHandler.IsReusable
Return False
End Get
End Property
End Class

OK - I've gotten somewhere - sort of but not really.

Using the Extensions, I've downloaded and installed the Extension Developer; then Created an Extension form Template (now available after installation of the Extension Developer) using "Integration Sample" as the Template cloned.

All good, but when attempting to connect to it (using either get or post to http://%URL%/App_Extensions/%UID%/Service.ashx/FindOrCreateSession/Test1/SessionCode) as the sample codebase provides, I get a 500 error. Any ideas or help on this?

Calling code from Client Application (tried with and without the credentials)

Dim request As WebRequest = WebRequest.Create("http://" & URLOrIPAddress & "/App_Extensions/" & UID & "Service.ashx/FindOrCreateSession/Test1/SessionCode")
request.Method = "GET"

Dim credC As New CredentialCache
credC.Add(request.RequestUri, "Basic", New NetworkCredential("UserAllowed", "Password for User"))
request.Credentials = credC

' Get the response from the Request Object
Dim response As WebResponse = request.GetResponse()

' Get the stream (through a stream reader) containing content returned by the server.
Dim dsReturn As Stream = response.GetResponseStream()
Dim reader As New StreamReader(dsReturn)
Dim responseFromServer As String = reader.ReadToEnd()

As of ~6.0ish we no longer accept parameters within GET requests for security reasons.

Instead, try POSTing your request with a payload containing the SessionCode.
