Title: netwebclient : IPv6 addresses and port
Post by: AtoB on July 25, 2026, 07:38:33 AM

(Using nettalk 14.38 and stringtheory 3.86)

I'm trying to get a webclient GET working with an IPv6 address (::1) and a specific port (8090), like this

::1:8090/yadayada

I've activated the LoggingOn property and it shows it reverts to port 80.

I think (!) the methods : .URLHostOnly and .URLPortOnly in stringtheory get confused by the use of "::" for the IPv6 address.

Maybe it needs to get the last ":" in the Host part of the url in order to seperate the port?

When I change:

    e = self.findChar(':',p,,pURL)

To:

    e = INSTRING(':',pURL,-1,s)

In both methods, it works (but I'm not sure wether this introduces side effects ...)

B.t.w. (local) server is IPv6 and via a browser (using [::1]:8090/yadayada) a get a valid response (and the server name shows up as "::1" in Nettalk)

Hi Ton,

I think you answered your own question;

>> ::1:8090/yadayada

that's not correct syntax.

>> using [::1]:8090/yadayada

that is correct syntax. If you are adding a port you need to add [ ]

Hi Bruce,

hmm ...

I tried the brackets around het ::1 part, but then the "server" becomes "[" (which is expected with current Stringtheory code as far as I can tell as there is no code that accounts for the brackets per se and it looks for the ":" from left to right).

Both "::1:port" and "[::1]:port" don't seem to work.

I've attached a screenshot of some debugview (in yellow the original request and the server part netwebclient resolves to)

Am I missing something still?

Regards,
Ton

Hi Ton,
I've made a new StringTheory build (3.88) which should take care of this for you.

Cheers
