Aloha!

I'm having some trouble re-writing some code for Umbraco v8 that was originally implemented for v7.

In short, I have an Http Module that rewrites a bunch of paths in order to accommodate a custom UsersMembershipProvider. The intent of the provider is to allow us to enforce stricter business rules regarding the user's password. Here's the original implementation:

using System;
using System.Web;

namespace Custom.Umbraco.Security.Modules
{
    public class PasswordRequirementsModule : IHttpModule
    {
        public void HandleLoginRequest(object sender, EventArgs e)
        {
            var context = ((HttpApplication)sender).Context;
            var url = context.Request.Path.ToLower();

            if (url.ToLower().Contains("/umbraco/backoffice/umbracoapi/authentication/postlogin"))
            {
                context.RewritePath("/umbraco/Api/CustomAuthentication/AuthorizedPostLogin");
            }
        }

        public void HandleSectionsRequest(object sender, EventArgs e)
        {
            var context = ((HttpApplication)sender).Context;
            var url = context.Request.Path.ToLower();

            if (url.Contains("/umbraco/backoffice/umbracoapi/section/getsections"))
            {
                context.RewritePath("/umbraco/backoffice/UmbracoApi/CustomSection/GetAuthorizedGetSections");
            }
        }

        public void HandleDashboardRequest(object sender, EventArgs e)
        {
            var context = ((HttpApplication)sender).Context;
            var url = context.Request.Path.ToLower();
            var queryString = context.Request.QueryString;

            if (url.Contains("/umbraco/backoffice/umbracoapi/dashboard/getdashboard"))
            {
                context.RewritePath("/umbraco/backoffice/UmbracoApi/CustomDashboard/GetAuthorizedDashboard?section=" + queryString["section"]);
            }
        }

        public void Dispose()
        {
            //throw new NotImplementedException();
        }

        public void Init(HttpApplication context)
        {
            context.BeginRequest += new EventHandler(HandleLoginRequest);
            context.BeginRequest += new EventHandler(HandleSectionsRequest);
            context.BeginRequest += new EventHandler(HandleDashboardRequest);
        }
    }
}

My approach was to create a Component so that I can hook into the execution pipeline via the Initialize() and Terminate() methods, however, I don't know of any service that is executed for every single Backoffice request. Below is my 1st pass which only executes in the context of content being saved.

using System;
using System.Web;
using Umbraco.Core.Composing;
using Umbraco.Core.Services.Implement;

namespace Custom.Umbraco.Security.Components
{
    public class PasswordRequirementsModule : IComponent
    {
        public void HandleLoginRequest(object sender, EventArgs e)
        {
            var context = ((HttpApplication)sender).Context;
            var url = context.Request.Path.ToLower();

            if (url.ToLower().Contains("/umbraco/backoffice/umbracoapi/authentication/postlogin"))
            {
                context.RewritePath("/umbraco/Api/CustomAuthentication/AuthorizedPostLogin");
            }
        }

        public void HandleSectionsRequest(object sender, EventArgs e)
        {
            var context = ((HttpApplication)sender).Context;
            var url = context.Request.Path.ToLower();

            if (url.Contains("/umbraco/backoffice/umbracoapi/section/getsections"))
            {
                context.RewritePath("/umbraco/backoffice/UmbracoApi/CustomSection/GetAuthorizedGetSections");
            }
        }

        public void HandleDashboardRequest(object sender, EventArgs e)
        {
            var context = ((HttpApplication)sender).Context;
            var url = context.Request.Path.ToLower();
            var queryString = context.Request.QueryString;

            if (url.Contains("/umbraco/backoffice/umbracoapi/dashboard/getdashboard"))
            {
                context.RewritePath("/umbraco/backoffice/UmbracoApi/CustomDashboard/GetAuthorizedDashboard?section=" + queryString["section"]);
            }
        }

        public void Initialize()
        {
            ContentService.Saving += this.HandleLoginRequest;
            ContentService.Saving += this.HandleSectionsRequest;
            ContentService.Saving += this.HandleDashboardRequest;
        }

        public void Terminate()
        {
            ContentService.Saving -= this.HandleLoginRequest;
            ContentService.Saving -= this.HandleSectionsRequest;
            ContentService.Saving -= this.HandleSectionsRequest;
        }
    }
}

Does anyone know of either a better way of accomplishing this or of a service that is guaranteed to be used for every request made to the Backoffice? Any advice is much appreciated!
