<section begin="desc" />Name of request header field<section end="desc" />
$Web_Hdr_Name retrieves the name of a field in a request header.
Syntax
<section begin="syntax" /> %RC = $Web_Hdr_Name( field_number ) <section end="syntax" />
$Web_Hdr_Name takes a single argument and returns a string, or null if the number references a non-existing field.
$Web_Hdr_Name is useful when writing generic server applications, when the server does not know what field name exists at a particular location in a request.
* Get the number of header fields. %X = $Web_Num_Hdr * Load the header field names into an array. FOR %Y FROM 1 TO %X %HDR_FIELD(%Y) = $Web_Hdr_Name(%Y) END FOR
