This is due to us having too many cookies, including the SignInMessage cookies. IdServer [default keeps the latest 5 SignInMessage cookies](https://github.com/IdentityServer/Thinktecture.IdentityServer3/blob/master/source/Core/Configuration/Hosting/MessageCookie.cs#L221). In our case, that's not always necessary. Although I do know that I can configure our web server to accept larger request headers, we'd like to be able to control how many SignInMessage cookies are being kept.\r\n\r\nI'm wondering if it's ok to add this option to the existing [CookieOptions](https://github.com/IdentityServer/Thinktecture.IdentityServer3/blob/master/source/Core/Configuration/CookieOptions.cs)? Or, conceptually, should it rather be an option on [AuthenticationOptions](https://github.com/IdentityServer/Thinktecture.IdentityServer3/blob/master/source/Core/Configuration/AuthenticationOptions.cs)? The default can still be 5 when not specified.\r\n\r\nI can create a PR for this, if you think the idea is ok. Just let me know. The change should be fairly straightforward and backward compatible.\r\n\r\n<!---\r\n@huboard:{\"milestone_order\":1010.0,\"order\":1014.5,\"custom_state\":\"\"}\n-->\r\n"},"comment":{"url":"https://api.github.com/repos/IdentityServer/Thinktecture.IdentityServer3/issues/comments/77712954","html_url":"https://github.com/IdentityServer/Thinktecture.IdentityServer3/issues/1010#issuecomment-77712954","issue_url":"https://api.github.com/repos/IdentityServer/Thinktecture.IdentityServer3/issues/1010","id":77712954,"user":{"login":"brockallen","id":649492,"avatar_url":"https://avatars.githubusercontent.com/u/649492?v=3","gravatar_id":"","url":"https://api.github.com/users/brockallen","html_url":"https://github.com/brockallen","followers_url":"https://api.github.com/users/brockallen/followers","following_url":"https://api.github.com/users/brockallen/following{/other_user}","gists_url":"https://api.github.com/users/brockallen/gists{/gist_id}","starred_url":"https://api.github.com/users/brockallen/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/brockallen/subscriptions","organizations_url":"https://api.github.com/users/brockallen/orgs","repos_url":"https://api.github.com/users/brockallen/repos","events_url":"https://api.github.com/users/brockallen/events{/privacy}","received_events_url":"https://api.github.com/users/brockallen/received_events","type":"User","site_admin":false},"created_at":"2015-03-07T22:03:24Z","updated_at":"2015-03-07T22:03:24Z","body":"I was shoveling snow in my driveway today...
