I am experiencing an issue with postback on the default site page (http://domain.com) without an acutal page in the url such as home.aspx. On this page only,  if you attempt a postback such as search input, survey, or even try to change the view from say edit to layout. The page just posts back to itself without changing or redirecting to search results etc. I have confirmed this with 2 different installs. No changes to url rewriting other than standard installation settings. The problem is not experienced on any other page and it works just fine for the default page as long as you append say home.aspx to the url in the browser. Support has been working on the problem but I thought maybe someone here has had some success with this issue.

DNN version 6.0.1.

Thanks

Did you ever find an answer to this?  We're having the same problem in DNN 6.1.5.  This seems to be a known issue in ASP.Net with .Net Framework 4.  But none of the solutions posted have worked for us in DNN.  No matter what we do, the action link in the form post is set to "/" for the default site page:

<form method="post" action="/" id="Form" enctype="multipart/form-data">

Once a user actually clicks through to a page or specifies the page name in the url, the action takes on the proper page name:

<form method="post" action="/Home.aspx" id="Form" enctype="multipart/form-data">

Without an appropriate page name, postbacks don't work on the default page.
