In DNS an SRV record really is a pretty generic form of telling a remote client where a specific service is hosted. At this moment I use it for allowing people to call me using a SIP client over the internet (works quite nicely).
One of the advantages of the SRV record is that you can specify a different port for the service and you can have multiple systems for the same (or the same system and multiple instances on a different port). So IFF it works you can have several webservers on a single system without any interferences.
So you could have this in your DNS:
_http._tcp SRV 10 50 8080 myserver.basjes.nl _http._tcp SRV 10 50 8081 myserver.basjes.nl
There is however one thiny snag to all this goodness ... I've not been able to find any HTTP, FTP, SMTP, ... clients that support it.
So other than SIP and the few other protocols mentioned in the Wikipedia page: Will the SRV record ever become really useful?
Or have I missed something?
Is there something better out there that does work?
