Detailed Description

Function Documentation

cache_accept_headers()

void cache_accept_headers	(	cache_handle_t *	h,
		request_rec *	r,
		apr_table_t *	top,
		apr_table_t *	bottom,
		int	revalidation
	)

Merge in cached headers into the response

Parameters

h	cache_handle_t
r	request_rec
top	headers to be applied
bottom	headers to be overwritten
revalidation	true if revalidation is taking place

Take two sets of headers, sandwich them together, and apply the result to r->headers_out.

To complicate this, a header may be duplicated in either table. Should a header exist in the top table, all matching headers will be removed from the bottom table before the headers are combined. The Warning headers are handled specially. Warnings are added rather than being replaced, while in the case of revalidation 1xx Warnings are stripped.

The Content-Type and Last-Modified headers are then re-parsed and inserted into the request.

cache_invalidate()

int cache_invalidate	(	cache_request_rec *	cache,
		request_rec *	r

This function returns OK if at least one entity was found and removed, and DECLINED if no cached entities were removed.
