How to disable self signed certificate in a HTTP.request in the HTTP.jl package.
`IOError(MbedTLS error code -9984: X509 - Certificate verification failed, e.g. CRL, CA or signature check failed during request`

To ignore this I just could use the key-value of
`require_ssl_verification = false`

is there a way how to set it globally, so even packages which use HTTP.jl would be usable with ignoring certificates?

Late, but it may help others
you need to set the environment variable `JULIA_SSL_NO_VERIFY_HOSTS` to your domains. See the official [NetworkOptions docs](https://docs.julialang.org/en/v1/stdlib/NetworkOptions/#NetworkOptions.verify_host) for more details
