Hi,

in v1.10.0 the following feature was added:

Add ability to pass custom headers on resource

When I updated to this version, my resources did not work any more. After a little bit of debugging, I noticed that the "Host" header was not sent as before, although I did not change anything in my configuration. So I removed the "Custom Host Header" and set it again, but no change. When I put "Host: xyz" into the "Custom Headers" field it started working again.

It looks like the new "Custom Headers" functionality breaks the old "Custom Host Header" functionality. I'm happy to use the new field instead, since it is much more flexible, but if the "Custom Host Header" does not work any longer, it should be removed from the UI.

Thanks for looking into this.
