Re: [jetty-users] Some questions regarding upgrade 9.3 -> 9.4

[Silvio Bierman <sbierman@xxxxxxxxxxxxxxxxxx>]

Hi Jan,

Thank you for your reply.

The scavenging defaults are fine with me. I was just thinking the log lines indicated I forgot something.

The session ids are a but clumsy for me since our system optionally has it's own JGroups-based clustering logic and therefore already prepends its own cluster prefixes (and a separating $-sign) to session ids. The current combination of prefixes looks very strange. Perhaps I could somehow set the cluster name to an empty String?

I already subclass the DefaultSessionIdManager and have something like:

override def newSessionId(request : HttpServletRequest,seed : Long) = mapping(super.newSessionId(request,seed))

where mapping is a String => String function that optionally prepends a cluster id prefix.

Can I get the raw session id directly somehow or do I need to trim off the length of the current cluster id?

Thanks again,

Cheers,

Silvio

Hi,

The node id has been used for quite a while now in jetty session ids to increase likelihood that they are unique across nodes in the cluster. If you'd like to change that then I suggest that you subclass the Defaultsessionidmanager and override the I'd generation method. 

The log lines you are seeing about the scavenger is just letting you know what the default settings are.  If you want to change it then make a Housekeeper instance, set its scavenge interval,  and set the Housekeeper onto the Defaultsessionidmanager.

Hello all,

I have upgraded to Jetty 9.4 and did some modifications to te embedding code. Things seems to be working fine but there are two things that bother me. I checked the embedding sample code but that did not give me any clues so if anyone can help me.:

1)

All generated session IDs now start with 'node0'.

I tried setNodeIdInSessionId(false) but that does not make the node0 prefix go away.

How can I get rid of this?

2)

When the server is started it logs

No SessionScavenger set, using defaults
Scavenging every 600000ms

What does that mean? Do I need to do something about that?
