There is a logical difference between POSTs and GETs that is documented in
the HTTP RFC.
GET is idem-potent POST is not.
What this means is that any use of GET shouldn't have side-effects while
uses of POST can have side effects. What this means in practice is that GETs
should ONLY be used for 'reads', a read can happen many times and return
exactly the same data. Whereas POST may be used for reads and 'writes'
(writing has the 'side-effect' of updating the thing you are writing to),
