I have been following the REST Discussion list for some months now.

I just signed up for it last night. Odd that it's on yahoo.
The http verbs that go a long way are
GET get the resource
POST create a new resource
PUT edit the resource
DELETE remove the resource
HEAD brief overview of the resource
Which seem to be everything you need to build a basic database with the
CRUD features:
Create
Retrieve
Update
Delete
(messy, coupled client) <---REST---> (messy, coupled server)
Yep.
The important point of REST is decoupling the client from the server
thus one gets benefits of scaling and cacheability.
I have been playing with Squid and the CacheFu Zope product. Smart
caching can really speed up your website. Note that Zope employs a
number of REST concepts. But it also uses cookies and sessions and some
other non-RESTful things.
Issues that often come up are sessions (not RESTful) and cookies
(also not RESTful) with observations like:
There are reasons to prefer putting info in URIs instead of cookies:
1. URIs can be bookmarked. Cookies can't.
2. URIs can be linked to. Cookies can't.
3. URIs can be e-mailed. Cookies can't.
4. URIs can be copied and pasted into a different browser. Cookies can't.
If I copy and paste to a friend a URI with my session info encoded in it
do they take over my session?
Now finally for an example of how one uses AJAX on the client side
with REST to build a responsive application see:
http://www.onlamp.com/pub/a/python/2006/02/23/using-rest-with-ajax.html
This is in my queue of things to read today. I'm thinking I like REST. I
am still wondering about AJAX. I'm still not able to come to terms with
programming in javascript.
You say you failed. The web appears to some to have been
successful. Whose advice should we follow?
Indeed. The proof is in the pudding and this pudding is pretty darn good.
