Add a note about anchor tags not working with the basic proxy

[Mk-Etlinger]

Hi there,

Hope this is helpful for other people. It's not immediately clear from the docs that when clicking on a relative link, to initiate an Oauth2 flow for example, the proxy doesn't work because of the Accept header is text/html.

Happy to re-word this to make it more clear. Let me know and I can fix.

Thanks!

Hi there,

Putting some activity here so that this doesn't get garbage collected. Open to changing this up but need feedback.

The issue:

The basic proxy can't initiate Oauth Flow for anchor tags because of the headers needed.

The Solve:

We need add the more advanced proxy and configure it to work properly. If this were in the docs, it would save the headache that I and many others have gone through.

Thanks!
