DropDownList SelectedIndexChanged event fails over the internet
<p>I have two ASP.net DorpDownLists in a web page. When the selection changes on the first drop down list, the client is expected to do a postback and the the server will populate the second drop down list based on the selection.</p>

<p>I have this page working as expected on the intranet but when it is accessed from the internet, the postback happens(I have verified the __EVENTTARGET with Burp Proxy and it is working) but the server is not calling the SelectedIndexChanged event. </p>

<p>Anybody ever faced something similar? Any suggestions or recommendations on how to resolve?</p>
