Someone raised the question of whether the LSID Browser for Firefox looks up DNS SRV records during the resolution protocol. In functional terms, the answer is YES, it does.

The cause of confusion is that the browser uses a web service somewhere else (at http://lsid.tdwg.org as of version 1.0.1) to do the lookup. That's because the Mozilla JavaScript toolkit doesn't provide SRV record lookup. Yes, it is a hack, but nevertheless it makes the client resolve LSIDs according to the specification.

You can disable that lookup by unchecking a box in the LSID Browser configuration. In that case, the browser will try to look up the authority using regular DNS A records (that "only in code" fallback mechanism that someone else mentioned in this thread). You can also configure the browser to provide your own local mapping between authority identifications to authority host.

   I hope this clarifies the issue.

   Cheers,

Ricardo

FireFox client doesn't seem to do this,

I stand corrected :-)
