Fixes #265 and #344
Problem 1 - #265 reports a CORs error which was caused because the SDK added telemetry headers only for every request that goes out. The redirected non-Graph endpoint complained about the unexpected SDK_Version header and caused a CORS error.
Solution for Problem 1 - This PR includes logic to check in the
TelemetryHandlerif the URL is a Graph URL and if yes process to add the telemetry headers. If the URL is a non Graph URL and the telemetry headers are present, then the headers are deleted.Problem 2 - #344 @peombwa Thank you for helping me reproduce this issue!
On redirection, the
RedirectionHandleris currently setting the AuthorizationHeader to undefined instead of completely dropping the header key.The existing code worked fine in a node environment but failed when using ExpressJS.
Solution for Problem 2 - This PR includes change in the
RedirectionHandlerto delete Authorization header key if present.
