Regular Expressions (Regex) on Load Balancers?

Load Balancing

Is it possible to use regular expressions on Digital Oceans Load Balancers? I currently use a droplet with HAProxy to achieve my goals but I would prefer if I could handle it outside of maintaining another droplet.

What I would like to do is forward a request to a specific droplet based on the URI.

Example:

api.site.com/v1/ => Server 1
api.site.com/v2 => Server 2

Hi @macman313

Yes, currently this functionality is not supported by the DO LB.

Would it be possible for you to use apiX.site.com/ instead, where X is the api version?
Because what you’re asking for is not load balancing, it’s more of a routing functionality.

Otherwise you might want to look at CloudFlare or similar services, since they support page rules, where you can configure it to use a specific server with some urls.
