Optimizing Performance on Sitecore Sites with Millions of Users (Continued)

I wrote a previous post here that talked about how to ensure good performance when you have a Sitecore site that allows for users that sign in to the site. Even before I wrote that post I knew of an issue that I resolved, which I did not mention in the post. The issue is w/ the JSS Dictionary Service and some other services JSS uses that requires running as sitecore\ServicesAPI user. The issue is that I suggest disabling the membership provider and Sitecore does a check against the membership provider to verify the user exists. I figured after all this time I would share a workaround for this issue in case anyone hits it. The simple solution is, just replace the DisabledMembershipProvider.

namespace BissTalk.Project.Site.Security
{
    using System;
    using System.Collections.Generic;
    using System.Globalization;
    using System.Web.Security;
    using Sitecore.Security;
    /// <summary>
    ///     overrides the default <see cref="DisabledMembersipProvider" /> to support returning anonymous user.
    /// </summary>
    /// <seealso cref="Sitecore.Security.DisabledMembersipProvider" />
    public class DisabledMembershipProviderForJss : DisabledMembersipProvider
    {
        /// <summary>
        ///     The list of all anonymous users.
        /// </summary>
        private static readonly Dictionary<string, MembershipUser> _users = new Dictionary<string, MembershipUser>
        {
            {"extranet\\anonymous", CreateUser("extranet\\Anonymous")},
            {"default\\anonymous", CreateUser("default\\Anonymous")},
            {"sitecore\\servicesapi", CreateUser("sitecore\\ServicesAPI")}
        };
        /// <summary>
        ///     Gets the user if it is an anonymous user's name, otherwise executes base GetUser.
        /// </summary>
        /// <param name="username">Name of the user.</param>
        /// <param name="userIsOnline">If the user is currently online.</param>
        /// <returns>The user, if it is an anonymous user's name, otherwise executes base GetUser.</returns>
        public override MembershipUser GetUser(string username, bool userIsOnline)
        {
            var name = username.ToLower(CultureInfo.InvariantCulture);
            return _users.ContainsKey(name)
                ? _users[name]
                : base.GetUser(username, userIsOnline);
        }
        /// <summary>
        ///     Creates a user.
        /// </summary>
        /// <param name="userName">Name of the user.</param>
        /// <returns>A user with the given user name.</returns>
        private static MembershipUser CreateUser(string userName)
        {
            return new MembershipUser("disabled", userName, userName, null, null,
                null, true, false, DateTime.MinValue, DateTime.MinValue,
                DateTime.MinValue, DateTime.MinValue, DateTime.MinValue);
        }
    }
}

And then in your web.config...

<membership defaultProvider="switcher" hashAlgorithmType="SHA1">
   <providers>
      <clear />
      <add name="sitecore" type="Sitecore.Security.SitecoreMembershipProvider, Sitecore.Kernel" realProviderName="sql" providerWildcard="%" raiseEvents="true" />
      <add name="sql" type="System.Web.Security.SqlMembershipProvider" connectionStringName="security" applicationName="sitecore" minRequiredPasswordLength="1" minRequiredNonalphanumericCharacters="0" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" />
      <add name="disabled" type="BissTalk.Project.Site.Security.DisabledMembershipProvider, BissTalk.Project.Site" applicationName="sitecore" />
      <add name="switcher" type="Sitecore.Security.SwitchingMembershipProvider, Sitecore.Kernel" applicationName="sitecore" mappings="switchingProviders/membership" />
   </providers>
</membership>

Problem Solved!!

P.S. This is example code. In real life you may want to put the list of users in a patch config rather than hard-coding them.
