What is this response header (x-Application-Context) stands for? is it specific to Spring framework?
what does the below header means?
X-Application-Context airtel-project-service:aws:27094
does it reveals any senstive information like hostname or port number?
回答1:
Spring Boot ApplicationContextHeaderFilter does add this header. Class description:
OncePerRequestFilter to add a X-Application-Context header that contains the ApplicationContext ID.
AppliationContext ID is a name for the deployed application that this context belongs to.
You can change the default behavior by setting management.add-application-context-header property to false.
management.add-application-context-header=true # Add the "X-Application-Context" HTTP header in each response.
Spring Boot resolved issue 1308.
