Should I use Url.Content() or ResolveUrl() in my MVC views?

Question

When building code like this:

<script type="text/javascript" src="<%=ResolveUrl("~/js/js.js")%>"></script>

or

<input type="image" src="<%=ResolveUrl("~/img/submit.png")%>" />

Should I use Url.Content or ResolveUrl()? What's the difference?

If you're using IIS URL Rewriting within your MVC application, e.g. internally treating http://yoursubdomain.example.com/MyController/MyAction as http://hosted.example.com/yoursubdomain/MyController/MyAction, Url.Content() will generate a correct subdomain-relative link. ResolveUrl() will generate an incorrect link in this situation.

Url.Content is more MVCish as it is the normal. ResolveUrl has been around since the beginning of ASP.NET.

@Darin Any reason to use one over the other? – Michael Haren Mar 10 '10 at 15:56

In an MVC application I would prefer `Url.Content`. It's kind of more unit-testable friendly. – Darin Dimitrov Mar 10 '10 at 16:16

I prefer to capture site root into local variable and reuse it

<% var siteroot = Url.Content("~/") %>

<script type="text/javascript" src="<%: siteroot %>Script/jquery-1.4.1.js"></script>
<script type="text/javascript" src="<%: siteroot %>Script/jquery.validate.js"></script>

It should save a few ms :)

This probably saves less than a few milliseconds. – Paul Mendoza Feb 09 '11 at 19:47
I don't think it's saving anything. It makes more sense to package your JS and CSS up using Gulp than micromanaging urls. – Jack Spektor Jan 31 '18 at 03:42
