Shortlist return URL working with the Shortlist plugin for Craft.

I'm trying to set the return URL after someone adds an item to their shortlist. 

i assume thats what this parameter is for...

&lt;a href="{{ item.addActionUrl({ 'return' : 'my-page-i-want-to-go-to' }) }}"&gt;add item&lt;/a&gt;


however that takes the user to a 404 page with the url of

mydomain.com/index.php/actions/shortlist/item/my-page-i-want-to-go-to


any ideas?
As mentioned in the comments on the Question, the solution here is to enclose your desired path with a url() function like so:

&lt;a href="{{ item.addActionUrl({ 'return' : url('my-page-i-want-to-go-to') }) }}"&gt;add item&lt;/a&gt;


The url() function will take your current SiteURL and append the provided path. You can view the offical documentation about url() here.
