project images download through proxy

[Shuhua Wu]

We have a xnat server that's not accessible from outside. We use a
server that's accessible from outside as proxy.
That is, http://www.predict-hd.net/xnat will redirect to
http://xnat.predict-hd.net:8080/xnat

The applet for project download images doesn't work. In the applet
page "<PARAM NAME="session0" VALUE="http://xnat.predict-hd.net:8080/
xnat/archive/catalogs/stored/1259954811142.xml">".

Can this be fixed please?

Thanks,
Shuhua

Shuhua,

Do other links work properly? Do the links in emails work properly?

What is the Site URL in Admin -> Default Settings set to?

Thanks Tim.

Other links work properly.

After set Site URL to www.predict-hd.net/xnat. It starts working. But
it won't work when we enter xnat.predict-dh.net:8080/xnat in browser
address from local network.

I started to download a project. After hours, it said "Download
complete". But it downloaded only 14GB of 26GB. I looked java console,
lots of IOException occurred, I copy two of them here:

Thanks, Shuhua.

The Project based downloader is in desperate need of refactoring. For starters, it needs to be using the REST API to download the files, rather than the old /archive/catalogs structure. The REST API is better tested.

I'll add this to our bug tracker.
