asp.net - Deny access to a persistent cookie -

-

if logs in on pc starbucks (for example) , accidentally check 'remember me' option thereby setting persistent cookie on pc, there way of denying cookie server without resorting changing cookie name in web.config?

i solved (a while actually) setting machinekey in web.config & changing when username/password changed:

 sub changemachinekey()     dim commandlineargs string() = system.environment.getcommandlineargs()     dim decryptionkey string = createmachinekey(64)     dim validationkey string = createmachinekey(128)     'httpcontext.current.response.write(decryptionkey + "<br />" + validationkey + "<hr />")     dim filename string = httpcontext.current.server.mappath("~/web.config")     dim xmlreader xmltextreader = new xmltextreader(filename)      dim xdoc xmldocument = new xmldocument()     xdoc.load(xmlreader)     xmlreader.close()      dim node system.xml.xmlnode = xdoc.selectsinglenode("//configuration/system.web/machinekey")     node.attributes.getnameditem("validationkey").value = validationkey     node.attributes.getnameditem("decryptionkey").value = decryptionkey     xdoc.save(filename) end sub  public shared function createmachinekey(byval numbytes integer) string     dim random byte() = new byte(numbytes / 2 - 1) {}     dim rng new rngcryptoserviceprovider()     rng.getbytes(random)     dim machinekey new system.text.stringbuilder(numbytes)     dim integer = 0     while < random.length         machinekey.append(string.format("{0:x2}", random(i)))         += 1     loop     return machinekey.tostring() end function

this forces sign in again since there 1 admin account works me!

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
