293701 - DNS SRV RR support

Status: RESOLVED DUPLICATE of bug 14328

(Core :: Networking, enhancement)

Description

[James McIninch]

User-Agent:       Mozilla/5.0 (compatible; Konqueror/3.3; Linux) (KHTML, like Gecko)
Build Identifier: 

The browser should check DNS SRV records for a site to obtain a server and 
port. For example, if DNS has the following record: 
 
_http._tcp.yourdomain.tld 60000 SRV 0 0 8080 serverA.yourdomain.tld. 
 
... the browser should interpret the URL 
 
http://yourdomain.tld/index.html 
 
as 
 
http://serverA.yourdomain.tld:8080/index.html 
 
(but show the former in the location bar). This is a well-documented feature of 
DNS that's becoming increasingly popular as it's being used by VOIP systems, 
SIP, Jabber, Zeroconf, and other protocols/software. 
 
It has the advantage of uncoupling the protocol from the arbitrary port 
assignment. Also, there may be multiple SRV records for a given hostname, which 
also allows for failover (that is, if you don't get a response from the first 
server in the list, try the next with the same path). 
 

Reproducible: Always
