Global.asax parent application and child application
<p>I'm working on some legacy code right now and I'm trying to move the Global.asax file up to the parent application and it will manage all of the children applications. Currently we have a Global.asax file in all of the children apps (bad). </p>

<p>When I try removing the Global.asax file from the child application, it does not find the parent application's Global.asax file unfortunately. Therefore I cannot stay authenticated within the child app. I was wondering if there is an easy fix to this.</p>

<p>Structure:</p>

<pre><code>parent app 
  files...
  childapp
    files..
    global.asax
  global.asax
</code></pre>

<p>I want the childapp to find the parent's Global.asax file. </p>

<p>Thanks guys! </p>

<p>EDIT:</p>

<p>Global.asax</p>

<p>(This is identical in the parent and child apps)</p>
