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.

Giuseppe Guerra	33f02839f0	Plugins: CallResource: Use canonical MIME headers when writing response (#58506) ... * Plugins: CallResource: use canonical MIME headers when writing response * Plugins: add tests for canonical mime headers and Set-Cookie filter * Removed extra new line	3 years ago
Ben Sully	480277f612	CallResource: don't set Content-Type header if status is 204 (#50780) ... Grafana's HTTPServer ensures that the Content-Type header is always set in the response to a CallResource call, but when the status code is 204 No Content this shouldn't be done; the body should be empty and no Content-Type header should be set. We ran into this in the Grafana ML plugin where we were sending an empty response with status 204, but the frontend client saw that the content type was JSON and tried to parse it, resulting in an error that made it to the JS console.	3 years ago
