asp.net mvc 3 - mvc3 cookie value not setting in ViewData page -

i have textbox , submit button people put in there enter 5 number pin , safed inside cookie 4 months not working im getting nothing out of it.. wrong.. first time trying cookies

read view

public actionresult index() {     //read cookie , send view model     var mycookie = request.cookies["mypreference"];     viewdata["prefvalue"] = mycookie.value;     return view(); } 

httppost

[httppost] public actionresult index(formcollection ss) {     // create cookie     httpcookie preference = new httpcookie("mypreference");     preference.value = ss["preffer"];     preference.expires = datetime.now.adddays(120d);     response.cookies.add(preference);     return view(); } 

the view

@using (html.beginform("seotips", "home", formmethod.post)) {     @html.textbox("preffer")      <input type="submit" value="submit" /> } @viewdata["prefvalue"] 

you have try

public actionresult index() {    httpcookie coo = new httpcookie("name");       coo["country"] = "india";       viewdata["prefvalue"] = coo["country"];     return view(); }
