[Seaside] Long submit problems with IE

[Carlos Lenz]

Hi Carl

Have this important distiction in mind:

GETs are not supposed to change your data, just to read it.
Conceptually it is called idempotence.
Check http://en.wikipedia.org/wiki/HTTP

So POST if you are changing something, even if it is small.

Cheers

Carlos
