RULI stands for Resolver User Layer Interface
RULI stands for Resolver User Layer Interface. It's a library built on top of an asynchronous DNS stub resolver. RULI provides an easy-to-use interface for querying DNS SRV resource records. The goal is to promote wide deployment of SRV-cognizant software. RULI aims to fully support SRV-related standards. There are bindings for PHP, Perl, Guile/Scheme, Java, and Lua. IPv6 is supported.
Now you can understand the benefits of SRV records and please see how RULI can help you.
SRV records are more complex than A records
Handling DNS SRV is not as simple as to deal with ordinary address records. When one performs a query for A records by calling gethostbyname(), he gets a list of addresses which should be contacted in the same order as they were received. For SRV records, there is an additional logic that must be applied to the records, based on their weight and priority, to discover the correct sequence for contacting them.
RULI can handle SRV records for you
The SRV logic is described in RFC 2782. Those who intend to use SRV benefits in their application are expected to implement that exact behavior. RULI can help here: it automatically performs all the SRV logic for you.
Keep focus on your application logic
Application developers probably want to spend time on their business logic; not dealing with the details of the DNS protocol or implementing the SRV specification.
RULI is a tested framework designed to properly fetch SRV records. It saves you time and head aches.
RULI is free as in 'free beer' and in 'free speech'
