As requested by Fermilab, Frontend and Factory should support also https

Frontend and Factory use their web servers for the staging and monitoring pages
  • staging must continue to use http, otherwise caching is not possible. Even if the files are small, the number of glideins is high and caching is essential
  • monitoring pages shoud use https by default

This means that:
- Apache configuration should be changed accordingly
- Should be possible to keep http for sites that desire so (provide instructions and/or alternative/commented config file)

The initial request from Fermilab was to move to https, but a move of everything is not possible for the reasons expressed above


#1 Updated by Marco Mambelli 3 months ago

Even if small in sizes, the files from the Factory and Frontend are downloaded by thousands of glideins. They rely heavily on HTTP Proxies. Https would increase the load on the server and the latency for all jobs. We found no way to cache the files with https. Proxies are considered to be Man In The Middle attacker.

Only the monitoring pages should be moved to https.
Https should be enabled and the http requests for the monitoring area should be redirected to https.

An exemption should be requested for the staging area

Tested also in the web browsers Safari and Chrome (especially in incognito windows to double-check possible cache issues)

Instructions to enable or disable HTTPS connections are in

Notice that module mod_ssl must be installed in advance to have https working. Also, due to issues with modules oversteps (and to make things easier for the installation), the mod_ssl load must be commented in ssl.conf as it's coming by default in the gwms-service.conf.
