Jmeter's doing the right thing. If you're testing wordpress, file a bug with them and tell them to fix their thing. If you're running an application server yourself, I'd suspect it's something wrong with your application server config.
You have the jmeter source, you could always change its behavior to do what you want and recompile it. I'd start with CookieManager.java: while (cookies.hasNext()) { Cookie cook = (Cookie) cookies.next().getObjectValue(); final long expiresMillis = cook.getExpiresMillis(); if (expiresMillis == 0 || expiresMillis > now) { // only save unexpired cookies writer.println(cookieToString(cook)); } } Well there's your problem! I can't guarantee that's the only thing that prevents expired cookies from being sent. I suspect there's probably also some code in httpclient that checks to see if they're expired before sending them back. I'd be really hesitant to change the behavior of the test environment to mask a bug you uncovered, though. Sending expired cookies IS a bug, and it's something the guys running the server should fix. -- Bruce Ide flyingrhenqu...@gmail.com
