NEXT_HTTP_HEADER function [HTTP]

Function 

Get the next HTTP header name.

Syntax 

NEXT_HTTP_HEADER (header-name)

Parameters 

header-name    The name of the previous header. If header-name is null, this function returns the name of the first HTTP header.

Usage 

This function iterates over the HTTP headers included within a request. Calling it with NULL causes it to return the name of the first header. Subsequent headers are retrieved by passing the function the name of the previous header. This function returns NULL when called with the name of the last header.

Calling this function repeatedly returns all the header fields exactly once, but not necessarily in the order they appear in the HTTP request.
