c# - MVC 2 Redirecting to Login page after POST, How can I fix this? -

i have basic controller create action both , post. works fine , renders page, however, post redirects me login page , data not save. using forms authentication i'm not using [authorize] attribute yet on of controller actions. works fine locally on machine, when publish server, error starts happening. here code create methods:

    [httpget]     public actionresult create()     {         var employee = new employeeviewmodel();         return view(employee);     }      [httppost]     public actionresult create(employeeviewmodel viewmodel)     {         var datamodel = viewmodel.transformtodatamodel();         allemployees.add(datamodel);         viewdata["successmessage"] = string.format("{0} added system", viewmodel.name);         return view("success");     } 

i using default aspnetsql membership/roleprovider/profileprovider , hosting on godaddy using iis 7.0. here main parts of web.config file:

<authentication mode="forms">        <forms          name="formcookie" protection="none" enablecrossappredirects="false" requiressl="false"        loginurl="~/account/logon" timeout="2880" defaulturl="~/home/index" path="/" />     </authentication>     <authorization>         <deny users="?"/>         <allow users="*" />     </authorization>     <identity impersonate="true"/> 

if has come across error before or knows going on, of immense help. thank you!

in asp.net mvc preferred way handle authorization using [authorize] attribute. <authorization> section in web.config should removed.
