asp textbox hangs at 4.1M characters. Need more cowbell

Question

I need 10M characters to paste in a textbox. From what I have read, System.int32 is possible, but for some reason, my code will do 4Million characters, but hangs at 4.1M characters which is around 2^22.

By hang, I mean it doesn't get to Page_Load(), nor btnPressed_Click(). Instead it just does nothing. I don't know how to figure out what it is doing......

Code attached. Thanks for reading and any leads!

Option Strict On
Imports System.Data
Imports System.Runtime.InteropServices.ComTypes
Imports Class1
Imports Oracle.ManagedDataAccess.Client


Partial Class _Default
Inherits MyPage
'Inherits System.Web.UI.Page

Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.PreLoad

    Beep()
End Sub



Protected Sub Page_PreRender(sender As Object, e As EventArgs) Handles     Me.PreRender

End Sub

Protected Sub Page_LoadComplete(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.LoadComplete

    validate_user()

End Sub


Public Class TempIsZeroException : Inherits ApplicationException
    Public Sub New(ByVal message As String)
        MyBase.New(message)
    End Sub
End Class



Protected Sub btnPressed_Click(sender As Object, e As EventArgs) Handles btnPressed.Click


    modalLoading.Hide()


End Sub



Protected Sub btnPressed_PreRender(sender As Object, e As EventArgs) Handles btnPressed.PreRender

End Sub



End Class

You may be running into the default max request length limits - maybe [this](http://stackoverflow.com/q/3853767/2278086) will help? — Mark, Aug 04 '16 at 15:47
