does the sigurl here https://osquery.readthedocs.io/en/stable/deployment/yara/ supports only https servers or also http servers?

I'm not sure it was tested with http servers, but did you try it and have issues?

i want to deploy a yara serverand just wanted if it possibe with http server

Ok, just be aware that there is currently risks associated with insecurely loading yara files https://github.com/osquery/osquery/issues/7720
