The REST of the Web

Response to: this is not REST

Using XmlHttpRequest means using javascript (& if you're supporting a wide variety of browsers, also probably means browser detection, etc). I'm trying to support the lowest common denominator which means that due to various browser constraints I'm limiting what I can use -- in addition I to keep things as simple as possible

Developing web services is a different matter. I can afford to be stricter about how the protocols are handled and let the client (for example, an XmlHttpRequest from a browser) deal with the interaction as best it can. But in this case, my intent is a simplified web app, so it's "a best-attempt", rather than "the best attempt".

Hope that clarifies things somewhat.

    "keep things as simple as possible"

    simple where? you're servlet now has a facade to allow you to pretend that it is a RESTfull interface. It isn't a RESTfull interface, it is REST + some pollution.

    sarissa (which I mentioned in my first note) is cross browser support for XmlHttpRequest so you don't need browser detection. Ok, you'd still be excluding lynx|links but were you including those anyway?

    Complicating the client side a little is preferred in REST, the view being that life is complicated enough on the server already.

    And you're article is titled "the REST of the web".

      Well, we'll have to agree to disagree, if you think that using javascript with sarissa is simpler than a standard html form. I don't
      see the use of a POSTed parameter, to subvert the http method at the server side, polluting the code as much as you seem to -- at least it's not setting an action directly within a URI (as Prescod notes in his Common Rest Mistakes).

      Do you have a reference discussing why client side complication is preferred for REST applications, because I've never come across anything with that recommendation. I'd certainly be interested in reading it.
