The server is diverting the client operator to an alternate asset, as showed by a URI in the Location header field, which is planned to give a roundabout reaction to the first request.
A client operator can play out a recovery demand focusing on that URI (a GET or HEAD demand if utilizing HTTP), which may likewise be diverted, and present the possible outcome as a response to the first demand. Note that the new URI in the Location header field isn’t viewed as proportionate to the successful request URI.
This status code is relevant to any HTTP technique. It is principally used to permit the yield of a POST activity to divert the client operator to a chose asset, since doing so gives the data comparing to the POST reaction in a structure that can be independently recognized, bookmarked, and stored, autonomous of the first request.
A 303 reaction to a GET demand shows that the starting point server doesn’t have a representation of the objective asset that can be moved by the server over HTTP. In any case, the Location field esteem alludes to an asset that is illustrative of the objective asset, to such an extent that creation a recovery demand on that other asset may bring about a representation that is helpful to beneficiaries without suggesting that it speaks to the first target asset. Note that responses to the inquiries of what can be spoken to, what representations are satisfactory, and what may be a helpful depiction are outside the extent of HTTP.
Aside from reactions to a HEAD demand, the representation of a 303 reaction should contain a short hypertext note with a hyperlink to similar URI reference gave in the Location header field.
