Issue/Introduction

Corguid coming from APM agents is not sent on to the Browser agent payload.
APM Agent is configured correctly and set cookie is arriving to the browser.

Environment

Release : 11.1.3

Component : APM Agents

Resolution

In the network tab we are seeing the corebrowserGUID.

From the browser agent all AJAX CORS errors, agent will NOT capture. because this is security level error and It will be thrown from the XMLXHRObject. this error will thrown from the browser engine before giving the response to XMLXHRRequest object.

We suspect that the route cause is only because of "Access-Control-Allow-Origin" header are not having the proper values because this only we are seeing this errors in browser console.

We should handle it ZULU proxy level. But these suggestion people are following.

1. :Access-Control-Allow-Origin put * for origin in Angular level or ZULU server level If we do not have any security issue.

2. zulu: ignored-headers: Access-Control-Allow-Credentials, Access-Control-Allow-Origin

3. Add CORS filter in ZULU proxy application
