Error 404 using asp.net web api

Question

I've got 2 projects: Core and Web.

Core project has API controllers, models, etc. Web project has html pages only.

I'm loading data from API using jQuery. When I do this exactly from Core project (created a view), everything is ok. But when I do this from Web project, I've got error 404, but Fiddler shows everything is ok.

Why is it so? What's a problem?

It's great that you found an answer and want to share it! Can you post it as an answer rather than an edit to the question though please? I've edited it out of the question for you but you can still see the older revision here: stackoverflow.com/posts/16632031/revisions. — Flexo - Save the data dump

I found the answer. That is because it's cross domain application. And it's necessary to implement CORS support. It can be done by two ways.

First. Add to section of web.config file next:

<httpProtocol>
 <customHeaders>
  <add name="Access-Control-Allow-Origin" value="*" />
  <add name="Access-Control-Allow-Headers" value="Content-Type" />
  <add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />
 </customHeaders>
</httpProtocol>

Second. Create custom MessageHandler. Like in this post
