Detailed Description

Macro Definition Documentation

ap_is_HTTP_CLIENT_ERROR

#define ap_is_HTTP_CLIENT_ERROR

(

x

)

(((x) >= 400)&&((x) < 500))

is the status code a client error

ap_is_HTTP_ERROR

#define ap_is_HTTP_ERROR

(

x

)

(((x) >= 400)&&((x) < 600))

is the status code a error (client or server)

ap_is_HTTP_INFO

#define ap_is_HTTP_INFO

(

x

)

(((x) >= 100)&&((x) < 200))

is the status code informational

ap_is_HTTP_REDIRECT

#define ap_is_HTTP_REDIRECT

(

x

)

(((x) >= 300)&&((x) < 400))

is the status code a redirect

ap_is_HTTP_SERVER_ERROR

#define ap_is_HTTP_SERVER_ERROR

(

x

)

(((x) >= 500)&&((x) < 600))

is the status code a server error

ap_is_HTTP_SUCCESS

#define ap_is_HTTP_SUCCESS

(

x

)

(((x) >= 200)&&((x) < 300))

is the status code OK ?

ap_is_HTTP_VALID_RESPONSE

#define ap_is_HTTP_VALID_RESPONSE

(

x

)

(((x) >= 100)&&((x) < 600))

is the status code a (potentially) valid response code?

ap_status_drops_connection

#define ap_status_drops_connection

(

x

)

Value:

                                   (((x) == HTTP_BAD_REQUEST)           || \
                                    ((x) == HTTP_REQUEST_TIME_OUT)      || \
                                    ((x) == HTTP_LENGTH_REQUIRED)       || \
                                    ((x) == HTTP_REQUEST_ENTITY_TOO_LARGE) || \
                                    ((x) == HTTP_REQUEST_URI_TOO_LARGE) || \
                                    ((x) == HTTP_INTERNAL_SERVER_ERROR) || \
                                    ((x) == HTTP_SERVICE_UNAVAILABLE) || \
                                    ((x) == HTTP_NOT_IMPLEMENTED))

should the status code drop the connection

AP_STATUS_IS_HEADER_ONLY

#define AP_STATUS_IS_HEADER_ONLY

(

x

)

Value:

                                     ((x) == HTTP_NO_CONTENT || \
                                     (x) == HTTP_NOT_MODIFIED)

does the status imply header only response (i.e. never w/ a body)?
