CacheKey with session Id mandatory?

Olivier · Post by **Olivier** » 28 Sep 2023, 11:59

Hello, I need your help to know if there is a solution to my problem :

Today, I a have an issue concerning the management of the CacheKey
My jnlp has the field jar like :

Code: Select all

<jar>{myUrl}?JSESSIONID={sessionID}></jar>

The jar is heavy (300 Mo)

So, when i download my Jar, icedteaweb create an entry in recently_used.cache with the full path of the jar set in the jnlp (so with the sessionId) like :

Code: Select all

::i=0\5::l={myUrl}?JSESSIONID={sessionID}::a=1695891392184::

If I disconnect my session and reconnect, I will change the sessionId so the cache will not work and the jar will be downloaded again. This is a shame because it is already present in the cache.

Is there a way/mechanism to adapt the CacheKey to change it with the name of the jar for instance as it is shown in the CacheViewer ?

Thanks for the time you'll take to answer me.
Regards,
Olivier

Which version of OpenWebStart are you using? Can you please send the log file?

You can buy Basic Suppport https://openwebstart.com/support/ to be able to post on a private channel.

My problem concerns this line :

Code: Select all

isCached: CacheKey{location={myBaseUrl}/{apiUrl}?JSESSIONID=ptq7q5c1amqks5nval7lcc7imr, version=null} = false

Because the jar {myBaseUrl}/{apiUrl} was already downloaded with another jSessionId. But the cache entry, as I explained in my first message depends on the sessionId.

Thanks

It seems you have edited the logs as the Jnlp file has some place holders.

I would like to see the Jnlp file that is actually processed by OWS.

In your Jnlp the url of jar file has been rewritten to include the session id. Is the Jnlp file generated on-the-fly by some dowloader servlet or something?

Is there some kind of SSO done before downloading Jnlp and there for it is necessary that all access to the server must have the session id? Please explain the you scenario i.e how come the urls in the jnlp file have been rewritten to have the sessionid.

I would request you to please purchase Support so that you can post your requests on a private channel and get a guaranteed response and fixes to your issues.

Olivier · Post by **Olivier** » 02 Oct 2023, 14:25

Yes,
I have edited the logs because of security reason.
Everything in {} are personnalData. However, it should be enough to understand what appens.
My jnlp file is build by my application. So, when the user download the file, the application fill the <jar> with the url to download the jar. But, to work, this url needs a sessionId due to security reason.
As it is a GET call, the application create the <jar> with the sessionId (found in the request done to build the jnlp file)
What I would like to know is : is there a way to add the sessionId field into another component
<jar href=myUrl>
<parameter="sessionId">rsoklofhej136qcq0unu2c7smf</parameter>
</jar>
Or something like that.
When I read the IceTea-web code, I don't see anything like that. It seems to me that the url is only set with the value of href. But maybe I aml wrong

I don't have any problem to download my jar. The jnlp works well.
BUT the cacheKey contains the jSessionId and it is a problem when i reconnect with a new session. It will download a new jar instead of using the one in the cache.

> As it is a GET call, the application create the <jar> with the sessionId (found in the request done to build the jnlp file)

I could reproduce the issue by generating a jar on the fly. I will investigate your issue and check if caching can be improved.

However, I would still request that you consider buying support. It makes it viable for us to maintain this software.
