Take a look at this blog post:

http://umbraco.miketaylor.eu/2010/11/03/url-rewriting-and-seo/

And this code snippet:

http://snipt.net/m1ketayl0r/umbraco-seo-url-rewriting

This uses the IIS7 Rewrite module...

Cheers,

I know this is old but that first link is inaccessible and the second refers to removing the trailing slash, not adding (as was originally requested).

Here is the rewrite rule that seems to work for me:

<rule name="AddTrailingSlashRule1" stopProcessing="true">
    <match url="(.*[^/])$" />
    <conditions>
        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
        <add input="{URL}" pattern="/umbraco_client" negate="true" />
        <add input="{URL}" pattern="/umbraco" negate="true" />
        <add input="{URL}" pattern="/install" negate="true" />
        <add input="{URL}" pattern=".axd" negate="true" />negate="true" />
    </conditions>
    <action type="Redirect" url="{R:1}/" />
</rule>

I have added this in config and working fine for me

<!-- Enforces Trailing Slashes for consistent URLs -->
<rule name="AddTrailingSlashRule1" stopProcessing="true">
<match url="(.*[^/])$" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
  <add input="{REQUEST_URI}" pattern="^/umbraco/" negate="true" />

</conditions>
  <action type="Redirect" url="{R:1}/" />
</rule>

I think you can config it in Umbraco In Config->umbracoSettings.config Look for addTrailingSlash in requestHandler

Not the answer you might want to hear, but if you install SEOChecker http://soetemansoftware.nl/seo-checker(commercial plugin). You can select this by one click and also makes sure all url's are lowercase and with/without extension etc.

Hope this helps,

This package is good except paid one

Thanks

I did not want to use a rewrite rule because it will catch all sorts of cases that it should not. I've written a content finder that will add trailing slash IF the content exists.

This is for Umbraco 7.5.11 so you may (but apparently not) need to change ContentFinderByNiceUrl to something that works in your version.

using System.Web;
using Umbraco.Core;
using Umbraco.Web.Routing;

namespace Terabyte.UmbracoWebsite.Infrastructure.ContentFinders
{
    public class MissingTrailingSlashContentFinder: IContentFinder
    {
        private readonly IContentFinder _baseContentFinderByNiceUrl = new ContentFinderByNiceUrl();

        public bool TryFindContent(PublishedContentRequest docRequest)
        {
            if (HttpContext.Current.Request.Url.LocalPath.EndsWith("/"))
            {
                return false;
            }

            if (_baseContentFinderByNiceUrl.TryFindContent(docRequest))
            {
                docRequest.SetRedirectPermanent(docRequest.Uri.EndPathWithSlash().ToString());
                return true;
            }

            return false;
        }
    }

    public class MissingTrailingSlashContentFinderApplicationStartup : ApplicationEventHandler
    {
        protected override void ApplicationStarting(UmbracoApplicationBase app, ApplicationContext ctx)
        {
            ContentFinderResolver.Current.InsertTypeBefore<ContentFinderByNiceUrl, MissingTrailingSlashContentFinder>();
        }
    }
}

If you wish to remove duplicate slashes from your urls replace the first few lines of the TryFindContent(...) with this:

        var path = HttpContext.Current.Request.Url.LocalPath;
        var rawPath = HttpContext.Current.Request.ServerVariables["UNENCODED_URL"]
                .Split(new[] {'?'}, StringSplitOptions.RemoveEmptyEntries)
                .First()
            ;

        if (path.EndsWith("/") && rawPath.Contains("//") == false)
        {
            return false;
        }

Umbraco 8 uses this rule

<rule name="Add trailing slash" stopProcessing="true">
          <match url="(.*[^/{2,}])$" ignoreCase="true" />
          <conditions>
            <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
            <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
            <add input="{REQUEST_URI}" pattern="^/umbraco/" negate="true" />
            <add input="{REQUEST_URI}" pattern="^/install/" negate="true" />
            <add input="{REQUEST_URI}" pattern="^/([0-9]+).aspx" negate="true" />
            <add input="{URL}" pattern="^.*\.(asp|aspx|axd|asmx|css|js|jpg|jpeg|png|gif|mp3|htm)$" negate="true" ignoreCase="true" />
            <add input="{URL}" pattern="/Base" negate="true" />
            <add input="{URL}" pattern="cdv=1" negate="true" />
          </conditions>
          <action type="Redirect" redirectType="Permanent" url="{R:1}/" />
        </rule>

Hmm, I don't think I like that. I think that means many 404s will be preceded by a redirect, and I still suspect it will catch cases it shouldn't.

is working on a reply...
