          Description

          To track usage, we configured bioviz.org to log requests for updates.xml - see: IGBF-3568.

          After implementing and deploying the new logging mechanism, AL checked the log.

          The log revealed that when IGB starts, it sends two requests for updates.xml, with two different user-agent strings.

          For this task, find out where in the IGB code these two requests are being made, and why MacOS and Windows user-agents are reported.

          Here are the relevant lines in the log:

          16.98.114.149 - - [04/Aug/2024:23:38:48 +0000] "GET /igb/releases/current/updates.xml HTTP/1.1" 200 7410 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64)"
          16.98.114.149 - - [04/Aug/2024:23:38:51 +0000] "GET /igb/releases/current/updates.xml HTTP/1.1" 200 1692 "-" "IGB/10.1.0; Mac OS X/14.3 (aarch64); en_US; Java/21.0.2"

              I suspect the reason for the double-access with different user agent strings is that the updating code, which comes from the installer, is responsible.
              We can check to see if IGB does a similar thing with other HTTP requests.
              Fore example, we are hosting default Quickloads on BioViz.org and so, when IGB starts, reaches out for that file. For example, here's a recent log entry:

              99.69.51.247 - - [19/Dec/2025:15:13:14 +0000] "GET /quickload/genome-in-a-bottle/contents.txt HTTP/1.1" 200 465 "-" "IGB/10.0.1; Mac OS X/15.7.2 (aarch64); en_US; Java/21.0.2"
