change access request page in sharepoint 2013

Question

If a user who don't have access to site, visits the site then he should see my custom page instead of Access Denied or Access Request page. Is this possible?

Answer 1

Yes it is! There is a very cool TechNet article on how to create a custom access denied page, however you need to have access a Front End server with a farm administrator account.

Apart from the Farm Adm account that also has the SharePoint_Shell_Access role for the farm configuration database, I think you would need some HTML/ASP knowledge.

Alternatively, you could create a HTTP Handler to intercept each request and redirect to your custom page. Check this blog post. And this is an code example of a Handler class.

public class CustomAccessDenied : ISPCustomRedirectHandler
{
    public string GetRedirectUrl(string key)
    {
        string serverRelativeUrl = string.Empty;

        var ctx = HttpContext.Current.Items["DefaultSPContext"];
        if (ctx != null)
        {
            serverRelativeUrl = ((SPContext)ctx).Web.ServerRelativeUrl;

            if (serverRelativeUrl.Equals("/"))
            {
                serverRelativeUrl = string.Empty;
            }
        }

        return string.Format("{0}/_layouts/15/myCode/CustomAccessDenied.aspx", serverRelativeUrl);
    }
}
