Spending a whole day troubleshooting why an environment variable appends in IIS rather than being replaced and what out of all our heaps of shit on our internal server is resetting the original value which is then being appended to. Kicker is, already have a docker solution which handles this use case 100% of time but we're too cheap to upgrade our internal environments from motherfucking Windows server 2008 so we can't use it. Save money at all costs!
