WPAD + DNS + APPLE = ???

[CHR1S]

I deliver my wpad file via DNS, it works everywhere, just not on the ipads/phones.

Can anyone else confirm this for me please?

Thanks

[CHR1S]

Or any mobile device for that matter, seems not to work on my S3 either

Have you tried using the DHCP option as well?
Can't remember off the of my head which devices support which but I know that not all devices support it via DNS, its worth having both enabled.

[CHR1S]

Its only IE/Chrome that works with DHCP.

If I point the ipad at the wpad url it works perfectly. Just not the auto DNS way

I can confirm if you host a proxy.pac file on Server 2008 R2 via IIS 7.5 it then works correctly for iPads.

I did read about some success with changing the auto config url to http://wpad/wpad.dat? for apple devices.

But do you point it at the wpad file with a URL or use DNS to deliver it?

I did read about some success with changing the auto config url to http://wpad/wpad.dat? for apple devices.

The URL if entered manually works fine, I want no user interaction so in BYOD situations they just connect to the wireless and DNS does the rest.

Oh I realise that, just trying to help with some troubleshooting, I was reading about Apple devices that could resolve http://wpad/wpad.dat if entered into a browser but not if trying to do it via DNS, it was reported that changing the auto config url to http://wpad/wpad.dat? solved the problem. I know that you don't want to have to do this on every device.

So if I host two wpad.dat files - wpad.dat and wpad.dat? on the server the ipads will pick them up?

Or am I missing your point?

[CHR1S]

Its the last day of term, im gonna need the big picture version today!!

On the iPad for example under proxy you specify Auto then enter: http://SERVERNAME:8082/proxy.pac for example.

But thats exactly what im trying to avoid doing.

I know, but as far as I'm aware Apple doesn't support it via the DNS method. Alternatively in an ideal world a transparent proxy would resolve these sort of issues.
