Real Server failing due to Response did not match error





Real Server failing due to Response did not match error in the logs.


Product: LoadMaster

Version: Any

Platform: Any

Application: HTTP/HTTPS

Question/Problem Description:

If the Apache CSP Header on the backend server is modified, the real server begins failing health checks despite the server returning a 200 OK response.

Steps to Reproduce:  
Error Message: Removing RS - Response did not match
Defect Number: LM-2344
Enhancement Number:  
Cause: The max header size for health checks is 8k characters.  The CSP header is pushing the health check over the 8k total header character limit.
Resolution: Modify the returned headers from the server to be below the 8k character limitation.
Workaround: Lower the LM health check to not be examining returned headers from the server.
