Re: [EP-tech] Redirect loop

Hi Dan,

Are you talking about one of the Docker containers discussed in https://wiki.eprints.org/w/Installing_EPrints_using_Docker

Looking at the Docker compose file this is running Apache but only on HTTP.  Therefore there should be no HTTP to HTTPS redirect loop issues.   I would advise configuring your Traefik proxy to rewrite HTTPS requests to HTTP.  If it does that it should all work as all th request sent through to the container should be HTTP and nothing in the container itself to redirect to HTTPS.  However, I have not tested this, so I would advise testing the Docker container image without running it through a proxy and see that you do not get redirect loops with this.  If you do, the issue will be something other that an HTTP to HTTPS redirect issue.

It would also be useful to know which version of EPrints you are running as there have been some recent changes to how cookies work (in EPrints 3.4.5+), which could be the reason behind your issue.  Although you are presumably not using Shibboleth authentication, this thread may be relevant to your redirect issues:

I am having what sounds like the identical problem described here:




And I see there is a solution proposed here:




(I just subscribed to this list, otherwise I would reply to the relevant emails)


But I am not sure the above solution will work for me, as I am not using Apache to handle HTTPS/SSL. I am running Eprints in a Docker Container in a Docker Swarm, and using Traefik  to terminate SSL connections for all apps in the swarm.


Any ideas on how I can resolve the seemingly endless redirects (an URL redirecting to itself with a 302 code) whenever I try and go to any URL that starts with /cgi/users ? I can’t move forward with my deployment until this is resolved as users cannot log in.
