Hi,
I have added some options to configure URLs used to do the online check.
I have added to options to set the URLs for IPv4 and IPv6 and another option
to disable the check of X-ConnMan-Status HTTP header.
The goal is to have this feature for boards that do not have access to Internet.
Best Regards,
Christophe Ronco

Hi Christophe,
First, thanks for taking the time and providing the patches.

This is a topic which pops up in regular basis. Marcel has a strong
opinion on why the URL should not be easily changed via a config file.
See the discussion here [1]. I don't think his opinion has changed since
then.

The goal is to have this feature for boards that do not have access
to Internet.
Recently, we added the config switches to disable it the online test
completely. see EnableOnlineCheck. When set to false, ConnMan wont try
to do the online test. The service will stay in the READY state. That
means the interface has been setup up and is ready to be used.
Thanks,
Daniel

OK, sorry to
have not found that before posting.
I won't bother you explaining my specific case and add my patches.

Maybe I got it wrong. You wrote "The goal is to have this feature for
boards that do not have access to Internet." So I wonder why the
configure --disable-wispr and EnableOnlineCheck=false connman.conf
shouldn't do the trick.
Thanks,
Daniel
