Recently I had a read of
an interesting post
by Lukas Smith (

) about the use of the DELETE method when building RESTful services. I wanted to get my thoughts down on this. Mostly to help myself, but if it helps you determine a better approach, then great.
I'm nowhere near qualified enough to preach, so this is by no means a "you should do it this way / my way is correct post", just food for thought. Besides, there are probably more questions here than answers.
So, Lukas highlights an interesting point ( which appears to still be debate ), about the correct status code to return upon the successful deletion of a resource, and whether that code should ever change for subsequent requests. In general debate is:
So first off let's try to determine what idempotence is in respect to HTTP and how it applied to REST services. According to RFC 2616 (section 9.1.2) :
"the side-effects of N > 0 identical requests is the same as for a single request"
So if you send a request with exactly the same input, the side-effects will be identical. But...
Initially I found the term "side-effects" threw me. It wasn't clear whether this side-effect needs to be considered for the server or the client. In respect to the DELETE method the initial request (which performs the deletion of a resource) will have completely different side effects to subsequent requests (that won't). Does this mean DELETE is NOT idempotent? Maybe. Maybe it means what it says, or maybe we're misunderstanding something.
If you were to look up the term idempotence you'll notice in other applications of the word it refers to the "resulting" effect of an operation. Given an input, the same output will always be returned. As a mathematical example: An operation of adding 10 (to any number) is idempotent. The result (per given input) will always be the same. So does idempotence mean identical results or identical operation? I honestly can't find a definitive distinction anywhere. According to wikipedia "it means that the modified state remains the same after the first call". So again, this has no bearing on the operational effect, just the end result. So let's extend our example:
This operation will always return the same result (per input), but it may randomly idle for 5 seconds, meaning the side effects are different. According to Wikipedia this operation IS idempotent . The state of $number will always be the same for every call. According to RFC 2616 this operation is NOT idempotent as the operational side effects can vary. I think it would also be correct to say that any operation that needs to check external state before it can determine a result is also not idempotent. Be it the current time, a file in a file system or a record in a database.
