It seems Caddy does not support wildcards/ expression matching in the reverse proxy's header_up.

For example this does not remove any headers:

header_up -X-SHIBBOLETH-*

This works as expected, but is limited in its use:

header_up -X-SHIBBOLETH-LOGIN

It'd be great if Caddy would support wildcards/ expression matching in the reverse proxy's header_up/ header_down.

Currently we have a mix of:

• Out of memory error.
• Out of memory error
• out of memory error
• out of memory

All these should be adjusted to use the same wording for consistency and it should also make the executable a little bit smaller 😄

We had an issue where an api user was using the incorrect parameters on an API call. Having this feature would have made the API fail instead of proceeding. The bug would been found earlier.

I can see where this would be a hassle on many cases, But it would be nice for new projects.

I suppose it could be a global config item that could be overridden at the individual action level:

It should allow rewriting http Host header like ngrok does with param -host-header=example.com
