I want to use POST in a idempotent (how like that word!) way, thus i
have no side-efects here. The problem is i probably will have lots of
data to pass, longer than can fit in a URL. Specifically to my
problem, i want to pass SQL SELECT clauses tha can be somewhat big,
and also connection strings.

Can there be a simpler solution?
