External aliases

This morning, one of my collegues noticed that you couldn’t use Aliases for external linking. Well… that sounds likea challenge for me :).
The following code is not supported, should work with 5.2 and is extremely unoptimised :P!

using System;
using Sitecore.Pipelines.HttpRequest;
using Sitecore.Data.Items;
using Sitecore.Data.Fields;

namespace LECTRIC.SC.Pipelines
class ExternalAliasResolver : AliasResolver
public new void Process(HttpRequestArgs args)
if (Sitecore.Configuration.Settings.AliasesActive &&
Sitecore.Context.Database != null &&
Item aliasItem = Sitecore.Context.Database.GetItem(“/sitecore/system/Aliases” + args.LocalPath);
if(aliasItem != null)
LinkField linkField = aliasItem.Fields[“Linked item”];
if (linkField != null && !linkField.IsInternal)

Getting it to work, you should replace
<processor type=”Sitecore.Pipelines.HttpRequest.AliasResolver, Sitecore.Kernel”/>
<processor type=”LECTRIC.SC.Pipelines.ExternalAliasResolver, LECTRIC.Sitecore”/>
in the httpRequestBegin-pipe line in the Web.config.

Notice that this will decrease the preformance of a request(dnot dramatical, but a little) and that links should be fileld in the right way(‘Insert External link’) in the aliases section. And as you can see, the Alias-folder is hardcoded as it isn’t defined in the web.config. Suggestions for optimising are welcome…

  1. Dear Alex,

    I’ve just used this piece of code for one of our customers and it works fine. 🙂

    You are hereby granted another Sitecore-award.

    Best regards,

  2. Great post, it would be very handy if there were to be a helper method within Item object that you can call to give you the first or a list of aliases assigned to an item. I’ve stumbled across this post as i’m just trying to get the alise URL assigned to the node.
