Infinte loop in session_start

[amirt]

Hello all,

I have a problem of infinite loop in my asp.net application in session_start.
it's located in global.asax and the code goes like this:

Try
Dim MyClassVars As MyClassVarsClass = New MyClassVarsClass 
If Not HttpContext.Current.Request.Cookies("MaxmindVar") Is Nothing AndAlso HttpContext.Current.Request.Cookies("MaxmindVar").Value <> "" Then
sessionVisitor.InitializeSession(Request, Request.ServerVariables, Session, True, True, HttpContext.Current.Request.Cookies("MaxmindVar").Value)
Else
sessionVisitor.InitializeSession(Request, Request.ServerVariables, Session, True, True, PayoutsVars.MaxMindString)
End If
Catch ex As Exception
Log("MyClass", "SessionVisitor Problem. " & ex.ToString, False)
End Try
                
MyClassVars.SessionId = "pyhyt" & Session.SessionID
Dim requestedURL As String = Request.Url.ToString
If requestedURL.IndexOf("tid=") = -1 Then
    ' check if the url has something in the querystring, and handle accordingly
       Dim token As String = MyHashing.cmpHashHandler.CreateToken(Session.SessionID)                            
      MyClassVars.Token = token
       MyClassVars.MaxMindString = "US"                                    
       MyHashing.cmpHashHandler.AddNewRecordToSortedList (token,               MyClassVars)
    If requestedURL.IndexOf("?") > -1 Then
        requestedURL = requestedURL & "&tid=" & token
     Else
         requestedURL = requestedURL & "?tid=" & token
    End If
End If                
Response.Redirect(requestedURL)
Response.AppendToLog("SessionStart")
End If

when i run my app. it gets into this loop in this function.
I have the same code exactly in my laptop and no problem there so I guess the different machine may cause the problem, maybe I'm missing something? the iis configuratrion is also the same...
help?

You need to show more code...

[amirt]

this is the code...
remarking it solves the problem (but I need this code...)

[DataMiser]

Just a guess but is it possible that the initializesession is causing the session start to fire again?

[amirt]

nope.
I correct myself -
only this code shoyld be remarked to solve the problem:

MyClassVars.SessionId = "pyhyt" & Session.SessionID
Dim requestedURL As String = Request.Url.ToString
If requestedURL.IndexOf("tid=") = -1 Then
    ' check if the url has something in the querystring, and handle accordingly
       Dim token As String = MyHashing.cmpHashHandler.CreateToken(Session.SessionID)                            
      MyClassVars.Token = token
       MyClassVars.MaxMindString = "US"                                    
       MyHashing.cmpHashHandler.AddNewRecordToSortedList (token,               MyClassVars)
    If requestedURL.IndexOf("?") > -1 Then
        requestedURL = requestedURL & "&tid=" & token
     Else
         requestedURL = requestedURL & "?tid=" & token
    End If
End If                
Response.Redirect(requestedURL)
Response.AppendToLog("SessionStart")
End If

my guess it's something with the response.redirect...
any ideas anyone??

Have you tried the code like this ...

MyClassVars.SessionId = "pyhyt" & Session.SessionID
Dim requestedURL As String = Request.Url.ToString
If requestedURL.IndexOf("tid=") = -1 Then
    ' check if the url has something in the querystring, and handle accordingly
       Dim token As String = MyHashing.cmpHashHandler.CreateToken(Session.SessionID)                            
      MyClassVars.Token = token
       MyClassVars.MaxMindString = "US"                                    
       MyHashing.cmpHashHandler.AddNewRecordToSortedList (token,               MyClassVars)
    If requestedURL.IndexOf("?") > -1 Then
        requestedURL = requestedURL & "&tid=" & token
     Else
         requestedURL = requestedURL & "?tid=" & token
    End If
    Response.Redirect(requestedURL)
End If                
Response.AppendToLog("SessionStart")
End If

you should only need to redirect if you alter the url ....
