RECEIVING COOKIE INFORMATION
|
|||
|
============================
|
|||
|
|
|||
|
struct CookieInfo *cookie_init(char *file);
|
|||
|
|
|||
|
Inits a cookie struct to store data in a local file. This is always
|
|||
|
called before any cookies are set.
|
|||
|
|
|||
|
int cookies_set(struct CookieInfo *cookie, char *cookie_line);
|
|||
|
|
|||
|
The 'cookie_line' parameter is a full "Set-cookie:" line as
|
|||
|
received from a server.
|
|||
|
|
|||
|
The function need to replace previously stored lines that this new
|
|||
|
line superceeds.
|
|||
|
|
|||
|
It may remove lines that are expired.
|
|||
|
|
|||
|
It should return an indication of success/error.
|
|||
|
|
|||
|
|
|||
|
SENDING COOKIE INFORMATION
|
|||
|
==========================
|
|||
|
|
|||
|
struct Cookies *cookie_getlist(struct CookieInfo *cookie,
|
|||
|
char *host, char *path, bool secure);
|
|||
|
|
|||
|
For a given host and path, return a linked list of cookies that
|
|||
|
the client should send to the server if used now. The secure
|
|||
|
boolean informs the cookie if a secure connection is achieved or
|
|||
|
not.
|
|||
|
|
|||
|
It shall only return cookies that haven't expired.
|
|||
|
|
|||
|
|
|||
|
Example set of cookies:
|
|||
|
|
|||
|
Set-cookie: PRODUCTINFO=webxpress; domain=.fidelity.com; path=/; secure
|
|||
|
Set-cookie: PERSONALIZE=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
|
|||
|
domain=.fidelity.com; path=/ftgw; secure
|
|||
|
Set-cookie: FidHist=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
|

|
domain=.fidelity.com; path=/; secure
|
|||
|

|

|

|
Set-cookie: FidDis=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
