[EP-tech] Configuring Azure Web Application Firewall (WAF) for eprints

[drn at ecs.soton.ac.uk (David R Newman)]

Hi Francis,

I don't have any significant knowledge about Azure WAF but EPrints 
should only require TCP ports 80 and 443 to be open to be fully 
functional.? (In some configurations only port 443 or 80 need be open).? 
You have tried turning off SELinux which rules out one potential issue.? 
My suspicion is that the Azure WAF might cause the apparent IP address 
of the connecting user to change between requests.? This would be 
supported by you saying that you seem to get logged out.? EPrints can be 
configured to not enforce the IP address being maintained during a 
session with the following configuration option in a configuration file 
in your archive's cfg/cfg.d/ directory:

$c->{ignore_login_ip} = 1;

and then reloading the Apache webserver.? If this does not help it is 
worth checking the error logs in /var/log/httpd/ to see if there is any 
obvious problem.? You want to check both error_log and ssl_error_log.? 
It may also be worth checking access_log and ssl_access_log whilst you 
are attempting to upload files to see if you can find any unexpected 
HTTP codes in the responses to your requests.

Regards

David Newman
