Almost forgot to mention, in terms of the cookiestore I basically performed
these actions:
// SERIALISE
...
final List<Cookie> cookies = getCookies(context);
logger.debug("{} Storing {} response cookies to cache id {}.",
new Object[]{id, cookies.size(), clientSessionId});
final List<Cookie> serialisableCookies = new
ArrayList<Cookie>(cookies.size());
for (Cookie cookie : cookies) {
logger.debug("{} Storing cookie '{}' to cache.", id,
cookie.getName());
serialisableCookies.add(new SerializableCookie(cookie));
}
// this is sent to memcached
cachedTargetSession.setTargetCookies(serialisableCookies);
...
private List<Cookie> getCookies(final HttpContext context) {
final CookieStore cookieStore = getCookieStore(context);
final List<Cookie> cookies = cookieStore.getCookies();
return cookies;
}
// DESERIALISE
final CookieStore targetCookieStore = new BasicCookieStore();
List<Cookie> cookies = cachedTargetSession.getTargetCookies();
// Add all the extracted cookies to the cookie store.
for (Cookie cookie : cookies) {
targetCookieStore.addCookie(cookie);
}
Cheers,
