Javascript - rpcHttpKey function always transfers payload using query params, instead of the utilizing the body

[MWFIAE]

Hey everyone,

I'm running into problems because the payload is always transferred in the query params in the rpcHttpKey function.
Therefore the amount of data I can transfer is very limited.

Other functions require a session that my backend server doesn't have and it seems like too much of a refactoring (with too many negative side effects) just to allow bigger payloads.

Have a great day!
