This order is - * important if any 'set' or 'unset' actions are used. For example, - * the following two directives have different effect if applied in - * the reverse order: - * - * Header append Author "John P. Doe" - * Header unset Author - * - * Examples: - * - * To set the "Author" header, use - * Header add Author "John P. Doe" - * - * To remove a header: - * Header unset Author - * - */ - -#include "apr.h" -#include "apr_strings.h" - -#define APR_WANT_STRFUNC -#include "apr_want.h" - -#include "httpd.h" -#include "http_config.h" -#include "http_request.h" - - -typedef enum { - hdr_add = 'a', /* add header (could mean multiple hdrs) */ - hdr_set = 's', /* set (replace old value) */ - hdr_append = 'm', /* append (merge into any old value) */ - hdr_unset = 'u' /* unset header */ -} hdr_actions; - -typedef struct { - hdr_actions action; - char *header; - const char *value; -} header_entry; - -/* - * headers_conf is our per-module configuration.
