Is an HTTP PUT request required to include a body?

Question

I\'m having trouble finding a definite specification of this in the standard. I have an HTTP client that\'s not including a Content-Length: 0 header when doing

Answer 1

A body is not required by the IETF standard, though the content-length should be 0 if there's no body. Use the method that's appropriate for what you're doing. If you were to put it into code, given

int x;
int f(){ return x; }

and a remote variable called r.

A post is equivalent to

r=f();

A put is equivalent to

r=x;

and a get is equivalent to

x=r;
