HTTP_RAW_POST_DATA

[Takashi]

Anyone know what this constant is for (Google searches are not bringing
anything that directly answers the question - what is it used for?)

Re: HTTP_RAW_POST_D ATA

It's not a constant, rather a predefined variable. The key (when used
within the globals array) contains, as suggested, the raw posted data
from a request.
