Greetings,
We are using Jetty 7.6.5 and are experiencing an odd error.
It appears that this is a Jetty error because when we switch to a different Servlet Engine (i.e. Resin) we do NOT see the same behavior.
But, of course, it could be just another case of pilot error
In a nutshell, we are seeing a Cookie "disappear".
Any ideas ??
Are others seeing this issue ??
Are we perhaps violating some Thread safety concern that we're unaware of ??
Thanks,
Chris Berry
Problem Description
--------------------------
This does not happen consistently and it happens primarily from an AJAX call (although not always)
Here's what we see:
When we execute the following code :
protected String readCookie(HttpServletRequest request) {
Cookie cookies[] = request.getCookies();
Cookie cookie = null;
if (cookies != null) {
for (Cookie nextCookie : cookies) {
if (cookieName.equals(nextCookie.getName())) {
cookie = nextCookie;
break;
}
}
}
String cookieValue = (cookie != null) ? cookie.getValue() : null;
log.info("READING SESSION ID FROM COOKIE (" + cookieValue + ") secure= "
+ ((cookie != null) ? cookie.getSecure() : "Undefined")
+ " [" + request.getRequestURI() + "]");
return cookieValue;
}
We do NOT get a Cookie. Even though we can see that there IS a Cookie Header present.
So we've had to fallback to this code (when the Cookie is NULL):
Where we can successfully pull out the Cookie value we need.
protected String readHeader(HttpServletRequest request) {
String cookieHeaderString = request.getHeader(COOKIE_REQUEST_HEADER_NAME);
if (null == cookieHeaderString || !cookieHeaderString.contains(DEFAULT_COOKIE_NAME)) {
log.info("READING SESSION ID FROM HEADER (No header for Cookie) [" + request.getRequestURI() + "]");
return null;
}
String cookieId = null;
try {
String[] cookies = cookieHeaderString.split(";");
for (String cookie : cookies) {
String[] cookieChunks = cookie.split("=", 2);
if (DEFAULT_COOKIE_NAME.equals(cookieChunks[0].trim())) {
cookieId = cookieChunks[1].trim();
break;
}
}
} catch (Exception e) {
log.warn("Error while retrieving session id from header string: " + cookieHeaderString, e);
}
return cookieId;
}
NOTE: We are not using any cross-domain AJAX requests. This occurs
with relative path URLs and also normal page requests.
