package subsonic

// The OpenSubsonic formPost extension requires the server accept API
// arguments via POST with an application/x-www-form-urlencoded body, in
// addition to the classic GET query-string form. This needs no
// dedicated handler: the router's dispatch (router.go) already calls
// r.ParseForm() before building params, and net/http's ParseForm merges
// URL query values and a url-encoded POST body into r.Form for any HTTP
// method — GET, POST, or otherwise — so every endpoint above already
// accepts either form for free.
//
// Precedence when the same key appears in both the query string and the
// POST body: net/http's ParseForm populates r.Form with POST-body values
// before query-string values, so params.Get (url.Values.Get, which
// returns the first entry) resolves a body value over a query value for
// the same key. This is deterministic — governed entirely by net/http's
// single parse of one request, not by any proxying/multi-parser
// ambiguity — and is asserted directly rather than silently relied upon;
// see TestFormPostBodyTakesPrecedenceOverQuery.
