Caching cookies in-memory.

See more HTTP Examples

Caching cookies in-memory. To automatically save cookies to an in-memory cache, set the CookieDir property equal to the keyword "memory". Also, set the SaveCookies property = _TRUE_. If the SendCookies property = _TRUE_, then any cached cookies are automatically re-sent with subsequent GETs and POSTs. Delphi ActiveX

// To cause cached cookies to be sent with 
// subsequent HTTP requests, set the SendCookies
// property = 1.
http.SendCookies := 1;

// Any methods that do a GET, POST, etc. will save 
// cookies to the CookieDir (which in this case is an 
// in-memory cache.

html := http.QuickGetStr('https://www.paypal.com/');

// To fetch the XML cookie(s) for a domain, call GetCookieXml:

xmlStr := http.GetCookieXml('paypal.com');

// It's content will look something like this:

// <cookies>

// If another HTTP request is sent, the cookies should
// be added:

// of the last HTTP request sent.
// The "Cookie" header field should be present.
