Application views using HTTP trickery

If the client makes a request, let's say this is an initial request to a resource that the client knows nothing about. It goes along and does a little something like this:

GET /foo HTTP/1.1
Accept: text/html

Programmable Hypermedia Client Blues (Part I)

In Restful Web APIs it is argued that one of the major problems with APIs (arguably regardless of whether they are RESTful) is that they don't convey enough semantics so a client unfamiliar with implementation details (media type, URL structures, HTTP methods etc.) could still make use of it. On the "human web" this isn't really a problem, as the book rightly points out, because humans are much better at making decisions despite considerable semantic gaps. For example, if a site contains a link with the text:

Click here to buy our most popular product!

It's easy for us to understand that we can click on it to purchase an item; a computer however would just see some additional markup and realize it's a link, but not where it points to, why or what it is:

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
