Macro Definition Documentation

APREQ_COOKIE_MAX_LENGTH

#define APREQ_COOKIE_MAX_LENGTH   4096

This macro is deprecated.

Maximum length of a single Set-Cookie(2) header.

Typedef Documentation

apreq_cookie_t

typedef struct apreq_cookie_t apreq_cookie_t

Cookie type, supporting both Netscape and RFC cookie specifications.

Function Documentation

apreq_cookie_as_string()

char* apreq_cookie_as_string	(	const apreq_cookie_t *	c,
		apr_pool_t *	p
	)

Returns a string that represents the cookie as it would appear in a valid "Set-Cookie*" header.

Parameters

c	cookie.
p	pool which allocates the returned string.

Returns

header string.

apreq_cookie_expires()

void apreq_cookie_expires	(	apreq_cookie_t *	c,
		const char *	time_str
	)

Set the Cookie's expiration date.

Parameters

c	The cookie.
time_str	If NULL, the Cookie's expiration date is unset, making it a session cookie. This means no "expires" or "max-age" attribute will appear in the cookie's serialized form. If time_str is not NULL, the expiration date will be reset to the offset (from now) represented by time_str. The time_str should be in a format that apreq_atoi64t() can understand, namely /[+-]?\d+\s*[YMDhms]/.

Remarks

Now time_str may also be a fixed date; see apr_date_parse_rfc() for admissible formats.

apreq_cookie_make()

apreq_cookie_t* apreq_cookie_make	(	apr_pool_t *	pool,
		const char *	name,
		const apr_size_t	nlen,
		const char *	value,
		const apr_size_t	vlen
	)

Returns a new cookie, made from the argument list.

Parameters

pool	Pool which allocates the cookie.
name	The cookie's name.
nlen	Length of name.
value	The cookie's value.
vlen	Length of value.

Returns

the new cookie

apreq_cookie_serialize()

int apreq_cookie_serialize	(	const apreq_cookie_t *	c,
		char *	buf,
		apr_size_t	len
	)

Same functionality as apreq_cookie_as_string. Stores the string representation in buf, using up to len bytes in buf as storage. The return value has the same semantics as that of apr_snprintf, including the special behavior for a "len = 0" argument.

Parameters

c	cookie.
buf	storage location for the result.
len	size of buf's storage area.

Returns

size of resulting header string.

apreq_parse_cookie_header()

apr_status_t apreq_parse_cookie_header	(	apr_pool_t *	pool,
		apr_table_t *	jar,
		const char *	header
	)

Parse a cookie header and store the cookies in an apr_table_t.

Parameters

pool	pool which allocates the cookies
jar	table where parsed cookies are stored
header	the header value

Returns

APR_SUCCESS.

APREQ_ERROR_BADSEQ if an unparsable character sequence appears.

APREQ_ERROR_MISMATCH if an rfc-cookie attribute appears in a netscape cookie header.

APR_ENOTIMPL if an unrecognized rfc-cookie attribute appears.

APREQ_ERROR_NOTOKEN if a required token was not present.

APREQ_ERROR_BADCHAR if an unexpected token was present.
