Giedrius Statkevičius	0485cf34cd	Plugins: Pass through dashboard/contextual HTTP headers to plugins/datasources (#60301) ... `X-Dashboard-Uid`, `X-Datasource-Uid`, `X-Grafana-Org-Id`, `X-Panel-Id` are very useful headers set by Grafana front-end that we would like to see on the data source as well. This is so that it would be possible to pinpoint from where slow queries are coming in Mimir/Thanos/Cortex/etc., for example. Relevant Mimir code lines: 0a94f26203/pkg/frontend/transport/handler.go (L182-L184) Tested manually that with these changes the headers are visible.	3 years ago
Marcus Efraimsson	c35c689a96	Plugins: Automatically forward plugin request HTTP headers in outgoing HTTP requests (#60417) ... Automatically forward core plugin request HTTP headers in outgoing HTTP requests. Core datasource plugin authors don't have to specifically handle forwarding of HTTP headers, e.g. do not have to "hardcode" the header-names in the datasource plugin, if not having custom needs. Fixes #57065	3 years ago
Marcus Efraimsson	6478d0a5ef	Plugins: Forward user header (X-Grafana-User) in backend plugin requests (#58646) ... Grafana would forward the X-Grafana-User header to backend plugin request when dataproxy.send_user_header is enabled. In addition, X-Grafana-User will be automatically forwarded in outgoing HTTP requests for core/builtin HTTP datasources. Use grafana-plugin-sdk-go v0.147.0.

Marcus Efraimsson	6dbe3b555f	Plugins: Refactor forward of cookies, OAuth token and header modifications by introducing client middlewares (#58132) ... Adding support for backend plugin client middlewares. This allows headers in outgoing backend plugin and HTTP requests to be modified using client middlewares. The following client middlewares added: Forward cookies: Will forward incoming HTTP request Cookies to outgoing plugins.Client and HTTP requests if the datasource has enabled forwarding of cookies (keepCookies). Forward OAuth token: Will set OAuth token headers on outgoing plugins.Client and HTTP requests if the datasource has enabled Forward OAuth Identity (oauthPassThru). Clear auth headers: Will clear any outgoing HTTP headers that was part of the incoming HTTP request and used when authenticating to Grafana. The current suggested way to register client middlewares is to have a separate package, pluginsintegration, responsible for bootstrap/instantiate the backend plugin client with middlewares and/or longer term bootstrap/instantiate plugin management.
