Why the put and delete method need methodoverride?

Question

What I mean is, why just let the put and delete as same as get and post,

they are all http method, when I want use put and delete,

I have to do some special trick, like use methodoverride,

Is there some technical problem about letting the same?

Answer 1

Are the PUT, DELETE, HEAD, etc methods available in most web browsers?

Why don't the modern browsers support PUT and DELETE form methods?

to sum it up: not all browsers support sending requests other than GET and POST, nor do all server software support other verbs than GET, POST and HEAD.
