Event-based pull replication fails for https request with Nginx and Apache.

Configuring Artifactory with event base pull replication with HTTPS (in the url) fails.

1. Set up a generic local repository on Artifactory-1
2. On Artifactory-2, set up a Generic Remote repository pointed to the local Artifactory-1 repo, using https:// in the url.
3. Configure Pull Replication as normal in the UI, enable Event based pull replication
4. Deploy a file to Artifactory-1 generic local
5. Observe that the file does not get pulled to the Artifactory-2 remote repository cache

Note that you will need to configure HTTPS via Nginx.

Currently the workaround for fixing this is adding the below parameter in the Nginx.

Proxy_buffering off;

Please see the below link for more details on the above parameter.
