I have some versioned folders of site files that we are handling through IIS. What I need to do is create a URL Rewrite that will redirect traffic from all requests that don't match the most recent version, TO that most recent version. I'm having a difficult time as RegEx are not my specialty and I have been working on it for the last week.
Here's an example of what I need.
Most recent version:
These urls have other routes off of the base as well (ex. https://testurl/v3/#/rout1)
I'm needing a regular expression that will say "Any requested url that is does not contain the /v4/ to REDIRECT to the https://testurl/v4/#
Can someone point me in the right direction?
