Question & Answer :
See this signifier:
<signifier act="http://www.blabla.com?a=1&b=2" technique="Acquire"> <enter kind="hidden" sanction="c" worth="three" /> </signifier>
Once submitting this Acquire signifier, the parameters a and b are disappearing.
Is location a ground for that?
Is location a manner of avoiding this behaviour?
Isn’t that what hidden parameters are for to commencement with…?
<signifier act="http://www.illustration.com" technique="Acquire"> <enter kind="hidden" sanction="a" worth="1" /> <enter kind="hidden" sanction="b" worth="2" /> <enter kind="hidden" sanction="c" worth="three" /> <enter kind="subject" /> </signifier>

If the technique is “acquire” and the act is an HTTP URI, the person cause takes the worth of act, appends a `?’ to it, past appends the signifier information fit, encoded utilizing the “exertion/x-www-signifier-urlencoded” contented kind.
Possibly 1 might p.c-encode the act-URL to embed the motion grade and the parameters, and past transverse 1’s fingers to anticipation each browsers would permission that URL arsenic it (and validate that the server understands it excessively). However I’d ne\’er trust connected that.
By the manner: it’s not antithetic for non-hidden signifier fields. For Station the act URL may clasp a question drawstring although.
