We have a new setup where we don't have internet access for our machines which we code on. (Stupid Idea in my opinion). Our Network Security department wants to know if the following URL is the only URL needed to allow firewall access to Microsoft's Symbol server.
msdl.microsoft.com/download/symbols
Is this the same URL that visual studio uses when it goes off and tries to download the needed .pdb files when debugging?
If you navigate to that url you will see you get an HTTP 302 response, which redirect you to another URL depending on what symbol you request for. I hope your firewall supports pattern matching for URLs. Here is a non exhaustive list i got from my windows server 2016 c++ project
