I missed this method. Is the following, the correct TXT entry?
IN TXT "service: wpad:http://...";
I think so. Never used it myself.
The full text reads:
5.4.5 DNS TXT service: Entries
Client implementations SHOULD support this mechanism. If the implementation language/environment provides the ability to perform DNS lookups on QTYPEs other than A, the vendor is strongly encouraged to provide this support. It is acknowledged that not all resolver APIs provide this functionality.
The client should attempt to retrieve TXT RRs from the DNS to obtain "service: URLs" contained therein. The "service: URL" will be of the following format, specifying a complete candidate CURL for each record located:
service: wpad:http://<HOST>:<PORT><PATH>
The client should first issue the following DNS query: QNAME=wpad.TGTDOM., QCLASS=IN, QTYPE=TXT
It should process each TXT RR it receives (if any) using each service:URL found (if any) to generate a candidate CURL. These CURLs should be pursued as described in Section 5.5 and beyond. Readers familiar with [1] should note that WPAD clients MUST NOT perform the QNAME=TGTDOM., QCLASS=IN, QTYPE=TXT lookup which would be suggested by that document.
