If I wanted to limit the data sent in POST to my server, would putting the function defining my specified data before the http request do that? Right now my complete msg object includes a jpg image (I don't want) and I can't seem to separate that from the other data (I do want) when being sent.

[banzobeans]

amazingly succinct full range of information!

Hi Terry and thanks for your videos that are very clear to me.
Is there a way to stop a flow from another flow? I haven't found much information on this and I'm wondering if this can be done and how.
