Some Suggestion's

[Rex]

Hey, A big thanks for this lovely project as its a big help in keeping asp classic communicating with modern APIs. I would like to suggest the following:

Loading JSON from URL

Line 31:
Should be GET rather than POST to work with most APIs like this one
Line 32:
Content-Type should be application/json; charset=UTF-8
Line 33:
I have never seen Charset in a header and Accept-Charset should no longer be used.
