action="" is what we want, from http://www.ietf.org/rfc/rfc2396.txt:
|
|
|
|
4.2. Same-document References
|
|
|
|
A URI reference that does not contain a URI is a reference to the
|
|
current document. In other words, an empty URI reference within a
|
|
document is interpreted as a reference to the start of that document,
|
|
and a reference containing only a fragment identifier is a reference
|
|
to the identified fragment of that document. Traversal of such a
|
|
reference should not result in an additional retrieval action.
|
|
However, if the URI reference occurs in a context that is always
|
|
intended to result in a new request, as in the case of HTML's FORM
|
|
element, then an empty URI reference represents the base URI of the
|
|
current document and should be replaced by that URI when transformed
|
|
into a request.
