             Summary: Too many requests to /dyn/closer.lua from NetBeans users behind an HTTP proxy
                 Key: NETBEANS-2204
                 URL: https://issues.apache.org/jira/browse/NETBEANS-2204
             Project: NetBeans
          Issue Type: Bug
          Components: updatecenters - Pluginportal
            Reporter: Bertrand Delacretaz


A  large organization with lots of users behind an HTTP proxy was recently banned from accessing *.apache.org servers due to too many requests to the following URL:

http://apache.org/dyn/closer.lua?action=download&filename=incubator/netbeans/incubating-netbeans/incubating-10.0/nbms/updates.xml.gz

Their proxy initiated more than 10'000 connections in 24 hours to that URL, causing an automatic ban by our infra defenses.

[~wave] rightly notes that this might be due to the NetBeans updates checker, if that's correct it would be good for someone from the NetBeans team to look at it in more detail to avoid such problems in the future. 

I suppose what needs to be done is to modify that {{closer.lua}} script (or use it differently if there's such an option already) so that its result is cacheable by an HTTP proxy.
