HTTP Cookies are discarded

[cofinoa]

The netcdf-java client applictions/utils are not storing cookies sent back by server.

The cookies returned from server are discarded creating a new session on every connection to server (DODS or HTTP).

For example, if user autentication is required, this makes that every request to server create a new session and therefore a new athentication process.

Are you using the current 4.6 branch? I made a whole
bunch of changes to properly handle cookies, but may
have screwed up something.
If you are using 4.6, then try this.

1. create a file ./.ocrc with this content:
   HTTP.COOKIEJAR=/tmp/cookes
   The /tmp/cookies can be any path.
   See if this works and let me know what happens

The issue is for 4.3.22.
I have tried 4.5.4 and 4.6 branches and cookies are working (tested with ToolsUI)

P.S.: I haven't tried the .ocrc solution, but BTW.... where is implemented this feature? I havn't find any reference to that in the code for the 4.6 branch

Sorry, my mistake. For some reason
I thought you were talking about netcdf-c.
Ignore my previous message.

For java, is there some reason you need to use 4.3.22?
In 4.5, we switched from Apache httpclient 3.x to 4.2.
It is possible that 3.x handled cookies incorrectly.

The netcdf-java 4.5 branches has issues with SSL providers. For more details about that see more details at issue #91 and my associated pull-request.

Also the JRE version >=1.7 could be a problem for our tools which are based on 4.3.22, and migrate to 4.5 it's planned but no in a short time.

I have tried to fix this in 4.3.22, but I need some help about where to look to try to debug and fix the issue. The HTTPSession and HTTPClient classes are a little bit obscure for me, mainly because I don't understand well how the httpclient library 3.1 works.

I would appreciate any help on this.

Hi Antonio:

It would be best for us to fix any problems that you are seeing on the
4.5/4.6 branch. I strongly recommend that you plan on upgrading. Let us
know if that is a possibility for you.

Since we do not have any way to test this ourselves, we need help
to test that it is working again in 4.6
