関数

const char* cache_create_key

(

request_rec *

r

)

create a key for the cache based on the request record this is the 'default' version, which can be overridden by a default function

CACHE_DECLARE

(

void

)

Merge in cached headers into the response

引数:

	h	cache_handle_t
	r	request_rec
	preserve_orig	If 1, the values in r->headers_out are preserved. Otherwise, they are overwritten by the cached value.

CACHE_DECLARE

(

int

)

Check the freshness of the cache object per RFC2616 section 13.2 (Expiration Model)

引数:

	h	cache_handle_t
	r	request_rec

戻り値:

0 ==> cache object is stale, 1 ==> cache object is fresh

int cache_remove_url	(	cache_request_rec *	cache,
		apr_pool_t *	p
	)

cache_storage.c
