getCookies
Retrieves (in Cookie-header form) the list of cookies that would be sent with a request to @uri.
If @for_http is true, the return value will include cookies marked "HttpOnly" (that is, cookies that the server wishes to keep hidden from client-side scripting operations such as the JavaScript document.cookies property). Since #SoupCookieJar sets the Cookie header itself when making the actual HTTP request, you should almost certainly be setting @for_http to false if you are calling this.
Return
the cookies, in string form, or null if there are no cookies for @uri.
Parameters
uri
a #GUri
forHttp
whether or not the return value is being passed directly to an HTTP operation
