Our Jenkins server is inside a secure environment with very limited external connectivity. I was able to finally convince the powers that be to create an exception in our proxy to allow the Jenkins master to contact the update center URL. However when I try to download, it redirects to a mirror which is not allowed.
Can I somehow tell the update center to NOT use a mirror or use a specific mirror that I can whitelist so I don't have to allow all possible mirror URLs?
Alternatively could I configure my own local mirror that I can use?
Thanks!!
