c# - ACS signout redirect not working -

working on acs sso, , signout process works fine. problem users remain on same page calls logout action, no matter have set redirect to

public actionresult logout() {     //load identity configuration     federationconfiguration config = federatedauthentication.federationconfiguration;      //get wtrealm wsfederationconfiguration section     string wtrealm = config.wsfederationconfiguration.realm;     string wreply = wtrealm;      //read acs ws-federation endpoint web.config     string wsfederationendpoint = configurationmanager.appsettings["ida:issuer"];      signoutrequestmessage signoutrequestmessage = new signoutrequestmessage(new uri(wsfederationendpoint));     signoutrequestmessage.parameters.add("wreply", wreply);     signoutrequestmessage.parameters.add("wtrealm", wtrealm);     string signouturl = signoutrequestmessage.writequerystring();      federatedauthentication.wsfederationauthenticationmodule.signout();     return this.redirect(signouturl);            } 

to execute action, page has click handler

$('#logout').click(function () {     $.post('@url.action("logout", "home", new { area = "" })'); }); 

a click correctly handled, logout action called , executed, site remains on calling page. network log shows call logout, no evidence redirect being attempted. in effort debug, have commented out redirect signouturl , tried redirecttoaction, redirecttoroute, , javascript call set window.location, none of seem fare better @ transferring user different page. missing?

what ended doing moving logout logic model class

public class logouthandler {     public string signout()     {         // load identity configuration         federationconfiguration config = federatedauthentication.federationconfiguration;          // wtrealm wsfederationconfiguation section         string wtrealm = config.wsfederationconfiguration.realm;         string wreply;         wreply = wtrealm;          // read acs ws-federation endpoint web.config         string wsfederationendpoint = configurationmanager.appsettings["ida:issuer"];          signoutrequestmessage signoutrequestmessage = new signoutrequestmessage(new uri(wsfederationendpoint));          signoutrequestmessage.parameters.add("wreply", wreply);         signoutrequestmessage.parameters.add("wtrealm", wtrealm);          federatedauthentication.sessionauthenticationmodule.signout();          return signoutrequestmessage.writequerystring();                 } } 

and having logout action call class return url, , redirect it. worked then, though don't know if there take account mobile

    public actionresult logout()     {         string signouturl = new logouthandler().signout();         return redirect(signouturl);     }
